File on 4 Investigates

File on 4 Investigates goes to Burnley in Lancashire to meet the young people and their families as they grapple with a ketamine epidemic. Used in human and veterinary medicine as an anaesthetic, experts say the drug is being used by increasing numbers of young people because it's cheap, easy to obtain and fashionable. But the health implications can be catastrophic - even fatal. It can cause mental health problems and irreversible bladder and kidney damage. Reporter Jane Deith hears from the Burnley vicar who has had to set up a support group for desperate parents; families whose children have experienced addiction, grooming, abuse and ill health and a young man who is being forced to undergo gruelling medical treatment for what’s known as “ketamine bladder”.Reporter: Jane Deith Producers: Jill Collins and Nicola Dowling Technical producer: Richard Hannaford Production coordinator: Tim Fernley Editor: Carl Johnston

With the billions he made at the expense of Russian taxpayers, Roman Abramovich bought six luxury superyachts over the years. Among them were the 162-metre-long Eclipse, with swimming pools, helipads and a missile defence system - and the Pelorus - sometimes lent to Chelsea footballers.They could each cost up to one and a half million dollars just to re-fuel. If they’d been declared as being for his own personal use, VAT would have been payable on costs like that. Instead, for more than a decade, tax authorities were led to believe the superyachts were being rented out to commercial customers. Financial investigations correspondent Andy Verity working with The Bureau of Investigative Journalism and The Guardian discovers that the firms renting the boats ultimately belonged to a trust held by - Roman Abramovich. Under the scheme devised for him, the sanctioned oligarch was hiring out his superyachts - to himself. Mr Abramovich has denied either directing or knowing of any deception.Reporter: Andy Verity Producer: Paul Grant Editor: Richard Vadon

Tens of thousands of children and young people across the UK suffer from severe forms of epilepsy which are resistant to treatment. For those with intractable epilepsy the options for treatment are limited and the risk of a catastrophic seizure is very real. But a growing body of evidence has pointed to cannabis having a positive effect on preventing seizures even in people who don't respond to other drugs. In 2018, medicinal cannabis was legalised following a high profile campaign led by parents of children with intractable epilepsy. They hoped the change in the law would lead to the drug becoming widely available on the NHS. But more than six years later File on 4 Investigates has discovered families going to extreme lengths to access a drug they say is keeping their children alive. Reporter Alastair Fee meets families who claim they have been forced to give their children illegal cannabis sourced online and follows others who regularly break the law importing medicine from the Netherlands.

The BBC's religion editor Aleem Maqbool hears from sexual abuse victims who say they were let down by senior church leaders for decades. Priest David Tudor was allowed to continue working within the Church of England - despite widespread concerns about his behaviour. Now there are calls for the Archbishop of York, Stephen Cottrell to resign over his handling of the case. He is due to take temporary charge of the church in the New Year following the resignation of the Archbishop of Canterbury, Justin Welby. The Church of England says File on 4's investigation into the case of David Tudor has 'revealed a catalogue of past safeguarding decisions, that allowed someone who was considered a risk in the 1980s to return to ministry in the 1990s.' This, they say, should never have happened.Reporter: Aleem Maqbool Producers: Steve Swann and Hayley Mortimer Technical producer: Craig Boardman Production coordinator: Tim Fernley Editor: Carl Johnston

Universities in the UK are facing a financial crisis, and with fears some may become bankrupt many institutions are making savings by cutting courses and staff numbers. Falling numbers of international students, who pay higher fees than their domestic counterparts, is partly to blame for the funding gap. File on 4 investigates if universities have become too reliant on overseas students, in some cases favouring the ability to pay over academic ability and overlooking the poor English language skills of some of those they enrol - even ignoring concerns over cheating. It also hears from a whistleblower about the multi-million-pound recruitment industry that feeds students from abroad into universities here – all at a cost.Reporter: Paul Kenyon Producer: Fergus Hewison Technical Producer: Craig Boardman Production Coordinator: Tim Fernley Editor: Carl Johnston

The government has pledged to stop using hotels to house asylum seekers. But in early November nearly three hundred people were moved into a hotel in Altrincham in Greater Manchester. The decision has provoked widespread concerns from the community and there are fears that far right protestors could target the premises. It follows violent demonstrations outside hotels in Rotherham, Hull, Tamworth, Manchester, Aldershot and Bristol in the summer. Hotel accommodation is often provided in some of the UK’s poorest communities where residents are already facing difficulties in accessing vital services. So what is the government’s plan to stop the use of hotel accommodation? And when will it end? File on 4 hears from some of those who live in the hotels – and from the communities who live nearby – and discovers who’s profiting from the asylum business.

A series of scandals involving babies and mothers being harmed in hospital have shaken some people’s confidence in NHS maternity care. As a result, many women are looking for alternatives when they give birth. Some are seeking help from outside of the NHS; including paying independent midwives, and even ‘freebirthing’, where they receive no medical support at all. But how safe is this, and is more regulation needed?

The number of people being recalled to prison after they’ve been released has nearly doubled in recent years. It has come at a significant cost to the public – but has it made the public significantly safer? Most recalls aren’t for further offending. Could the gains made by the early release scheme be undermined by the huge number of people being recalled to prison?Former prisoner and filmmaker Chris Atkins investigates the opaque world of prison recalls. He speaks to prison reform charities who say arbitrary recalls drag many further into a cycle of crisis and crime and follows one troubled prisoner over five years, who is recalled four times despite never being charged with any new crimes.Reporter: Chris Atkins Producer: Alys Harte Technical Producer: Richard Hannaford Production Coordinator: Tim Fernley Editor: Clare Fordham

Over three decades, a priest assessed as posing a risk of “significant harm” to children and vulnerable people worked in the Church of England. But allegations against him didn’t stick, leading to him remaining in post until after he was offered a substantial pay-off. The surprising manner in which he finally left in 2022 raises serious questions about the judgement of Church leaders.If you have been affected by sexual abuse or violence, details of help and support are available at bbc.co.uk/actionline.Reporter: Aleem Maqbool Producers: Steve Swann and Fergus Hewison Technical Production: Richard Hannaford Production Coordinator: Tim Fernley Editor: Carl Johnston

Camp Lejeune is a vast US Marine Corps base in North Carolina. It’s been in operation since the 1940s and covers a massive 240 square miles. But for years it hid a secret. For decades, its water supply was contaminated with harmful chemicals found to increase the risk of some cancers. It’s estimated that one million people might have been exposed to the toxic water. But it wasn’t just American personnel who were based at Camp Lejeune. Soldiers from all over the world - including from the UK - also spent time there on training exercises and exchange programmes. Emma Forde hears from the British veterans and their families who lived and worked on the base and have since suffered serious health problems or seen loved ones die from conditions associated with exposure to the water. But despite a compensation scheme for victims being widely reported in the US, there are concerns that those from the UK are still unaware of the serious health risks they were exposed to. And time is running out.Reporter: Emma Forde Producer: Andrew Picken Technical Producer: Richard Hannaford Production Coordinators: Ellie Dover & Tim Fernley Editor: Carl JohnstonImage: Royal Marine Captain Joe House and Captain Jonathan Lear handing over to each other at Camp Lejeune.

Project Rescue Children claims to save children from trafficking and abuse, but the BBC has uncovered evidence of false and misleading social media posts. The charity's director, Adam Whittington, has raised thousands of pounds from sponsors and donors around the world.

There are more empty homes than homeless households in this country. Why?Filled with cobwebs, windows broken, and rats scurrying about in their overgrown gardens, the UK has hundreds of thousands of ghost houses - properties where no one lives. The UK also has the worst homelessness problem in the rich world. So could we use those empty homes for the people in dire need of a home?Simon Maybin investigates the phenomenon of empty homes and, over nine months, follows the work of someone trying to turn unused properties into homes for families among the record numbers who are now homeless.Reporter/producer: Simon Maybin Technical producer: Neil Churchill Production coordinators: Ellie Dover & Tim Fernley Editor: Richard Vadon

New laws aimed at preventing protestors causing disruption, more severe punishments and fewer defences in court have led some to question if the freedom to protest is coming under threat. Josephine Casserly investigates the growing volume of prosecutions against environmental protestors and examines how the criminal justice system is dealing with such cases. She also examines the increasing use of private injunctions by corporations and public authorities to restrict protests at locations such as public roads and oil terminals. They say the orders are necessary to prevent disruption caused by tactics including walking slowly down roads and blocking entrances to businesses, but lawyers acting for protestors say they amount to a "privatised system of justice."

There are two compensation schemes for veterans who’ve suffered injury or illness as a result of service - the Armed Forces Compensation Scheme - or AFCS - and the War Pension Scheme. The schemes are managed by Veterans UK which is an organisation run by the Ministry of Defence.But veterans have long criticised both schemes. Some say they reject claims unfairly, and are slow to resolve them. File on 4 has been told in some cases it’s taken almost 12 years for a final decision to be made. How does the system work? And what is the impact on veterans who claim they have to fight for financial compensation for conditions they say are a result of their service? File on 4 hears from one ex-servicemen whose claim took over seven years to resolve, and from the family of another former soldier who took his life after his claim for PTSD was repeatedly turned down.If you are affected by anything in this programme, details of organisations offering support with mental health and self-harm, or feelings of despair, are available at bbc.co.uk/actionline.Producer: Vicky Carter Reporter: Datshiane Navanayagam Technical producer: Richard Hannaford Production co-ordinator: Tim Fernley and Ellie Dover Editor: Carl Johnston

In the headlines about NHS waiting lists, children don’t often get a mention. Yet hundreds of thousands are waiting to start hospital for treatment. Jane Deith investigates the reasons for the gap between adult and paediatric surgery. She hears from children whose conditions are deteriorating, some of whom could be left inoperable if they aren’t operated on soon. NHS leaders admit long waits can have life-long consequences for young people’s development and say hospitals are working hard to tackle the backlog.

The most senior family court judge in England has described the growing use of Deprivation of Liberty orders for vulnerable children as a 'crisis.' File on 4 hears from young people who were held under the order supposedly for their own safety. But they say they were under constant supervision, denied access to their phones and the internet and kept away from their families. Some say they were subjected to physical restraints and even supervised when they were having a shower.

There are some two million people with long Covid in the UK - and most of them - around one and a half million - have symptoms that interfere with day to day activities. Fatigue, breathlessness, heart palpitations and severe dizziness are just some of the conditions people experience.Currently there’s no test for long covid and it could be years before we know for sure how best to treat the condition. This struggle to get help is leaving some very unwell people desperate - and willing to try anything to get better. There are treatments to wash your blood, high pressure oxygen chambers normally used by deep sea divers. A rainbow of supplements. All with varying degrees of evidence. And perhaps most strongly dividing opinion - programmes that claim to retrain long Covid patients' brains to stop their symptoms. They say they can help people recover from illness by rewiring the brain using techniques to influence physical changes in the body. Rachel Schraer - the BBC's health and disinformation correspondent - hears from people with long Covid who say the programmes didn't work and in some cases made them feel worse. Others say they fully recovered. Reporter: Rachel Schraer Producer: Paul Grant Technical producers: Cameron Ward and Nicky Edwards Production co-ordinator: Tim Fernley Editor: Carl Johnston

Manchester City are dominating English football, with a trophy cabinet full of silverware. The club’s success has been bankrolled by money from Abu Dhabi. Now Newcastle United have followed in their wake, with backing from a Saudi consortium transforming a sleeping giant of English football into perhaps the world’s richest club. But with the money comes accusations that the clubs are being used to launder the reputations of repressive regimes accused of human rights abuses, and that the cash from the two oil rich states is being used to exert political influence locally and nationally in the UK.Reporter: Adrian Goldberg Producer: Fergus Hewison Technical Producer: Craig Boardman Production coordinator: Tim Fernley Editor: Carl Johnston

Three years ago, dozens of memory sticks were discovered in a sealed box at a school for children with special educational needs. There was 500 hours of footage which showed children being held in so-called 'calming rooms.' The videos showed the children being hit and denied access to a toilet. File on 4 investigates why a subsequent police investigation and an independent inquiry didn't lead to staff being sacked.

As the cost of living crisis continues to increase the strain on families, a record 142,000 children in England are homeless and living in what should be short term temporary accommodation. Children are being consigned to B&Bs and hotels, former office blocks - even shipping containers – some without a bed of their own, living among rats and cockroaches - conditions the children’s commissioner has condemned as Dickensian.

"Maria" ended up in A and E after being assaulted by her 11-year-old child. There’s nothing unusual about children being rude or sometimes abusive to their parents, particularly when they’re adolescents. But some parents are attacked and abused by their children on a regular basis. It’s a pattern of behaviour that can begin as young as three years old and become unmanageable by teenage years. Many parents remain silent out of shame and out of fear of the consequences if they seek help, worried that their child may be taken into care or criminalised. So it’s a hidden problem. The issue is now on the government’s agenda with a consultation that’s aiming to find a common definition for the issue. Jo Glanville talks to parents, practitioners and researchers about what happens in families when a child becomes violent, what should be done to support them and what lies behind this kind of behaviour.Presented and Produced by Jo Glanville Executive Editor: Bridget Harney Research: Maia Miller-Lewis Studio Manager: Jon Calver Actors: Jayne Ashbourne and Juliet Cowan A Loftus Media production for BBC Radio 4 Organisations in the programme offering information or support on child to parent violence:Family Lives Parentline family support and bullying helpline | Family Lives https://www.familylives.org.uk/how-we-can-help/confidential-helpline CAPA First Response Capa First Response | You are not alone - Capa First Response https://capafirstresponse.org/Talk Listen Change Young People’s Programmes - TLC: Talk, Listen, Change (talklistenchange.org.uk) https://talklistenchange.org.uk/project/young-peoples-programmes/Holes in the Wall HOLES IN THE WALL | documenting parent abuse https://holesinthewall.co.uk/

It’s a scandal that went uncovered for 30 years. Body parts and organs from former workers in the nuclear industry were systematically removed for research. But the families of those former workers were never told. The truth only came to light following a three year inquiry published in 2010. But was this practice contained to one industry, or was this happening on behalf of others too? News reports around the time of the Sellafield scandal claimed that organs of coal miners were also being routinely removed during post-mortems at the request of the then National Coal Board. So, was the coal industry involved in a similar scandal - and to what extent? And could the need to advance research and science ever be seen to outweigh the need for permission?Reporter and producer: Emma Forde Technical Producer: Richard Hannaford Journalism Assistant: Tim Fernley Editor: Clare Fordham

The case of Carla Foster made headlines last year after the mother-of-three was initially sentenced to two years in prison for taking abortion pills after the legal cut-off. Since then, several other women have appeared in English courts accused of having illegal abortions, with increasing numbers of women under police investigation. Reporter Divya Talwar hears from women who have been investigated on suspicion of procuring illegal abortions, meets one woman who was prosecuted and sentenced, and hears from a journalist who believes the law is proportionate. File on 4 reveals that in some cases, women who have experienced pregnancy loss and premature deliveries are also being investigated on suspicion of having illegal abortions. There have been growing calls from campaigners and MPs to scrap the Victorian law that criminalises abortion in England and Wales and replace with medical regulation instead - as is the case in Northern Ireland. While some say the law doesn’t need to be changed, others believe urgent reform is required so women involved are treated with compassion instead of being punished.Reporter: Divya Talwar Producers: Anna Meisel and Eleanor Layhe Technical Producer: Richard Hannaford Production Coordinator: Tim Fernley Editor: Clare Fordham and Carl JohnstonImage Credit: MartinPrescott\Getty

File on 4 tells the story behind the brutal killing of schoolgirl Brianna Ghey. She was attacked in a park near Warrington in Cheshire on a Saturday afternoon in February 2023. Two teenagers - Scarlett Jenkinson and Eddie Ratcliffe - who were obsessed with murder and torture, have been convicted of her murder. In the build-up to the killing, they exchanged text messages outlining details of their plan. The girl even wrote a detailed plan of how they would go about the murder which was found by police in her bedroom. File on 4 has discovered how she had been part of a 'managed move' to Brianna's school after she poisoned a younger girl with a cannabis-infused 'gummy' and didn't tell her what was in it. The 13-year-old became very poorly and the police were alerted. The victim's family decided against further action and the matter was referred back to the school. Scarlett Jenkinson was suspended for five days and later transferred to Brianna's school where the two girls became friends. However, before accepting Jenkinson on their register, the school was not given all the details of the incident involving the cannabis sweet. Warrington Borough Council says a child safeguarding review is underway and it will examine all of the issues - including the circumstances surrounding the managed transfer.

The story of the Post Office IT scandal has gained new momentum in the wake of an ITV dramatisation about how dozens of subpostmasters were falsely accused of theft and fraud and hauled through the courts. After 20 years, campaigners won a legal battle to have their cases reconsidered and in 2019 the Post Office lost a High Court battle and agreed to pay nearly £60 million to more than 550 of its staff. Some ended up in prison, others bankrupt - many more have been left with their health and reputations in ruins. A public inquiry is ongoing, but many victims are still fighting to have their convictions overturned or to secure full compensation.In this episode of File on 4 - updated since its first broadcast in February 2020 - Hayley Hassall meets some of those whose lives were destroyed.

Felicity Hannah explores how climate change is leaving communities 'uninsurable' because of the rising risk of them being hit by extreme weather events.She speaks to one businessman living in 'Hurricane Alley' in Louisiana, who has seen his premiums rise by $200,000 in just three years, and learns how many residents are now having to run the risk of living without insurance, because the cost is just too high. In Australia, she speaks to residents resigned to the fact that their hometown is considered too much of a risk for the insurance industry. Instead, the government has bought their homes and they have been forced to leave. In the UK too, Felicity meets business owners already deemed 'uninsurable' because of the frequency of flooding they have faced. Meanwhile British homeowners relying on a temporary fix that has helped reduce their premiums must hope flood defences are built before time runs out.

Lucy Letby was allowed to continue working with new-born babies despite her colleagues raising concerns about her for months. Her conviction highlighted how NHS executives put the reputation of the Countess of Chester NHS Trust ahead of patient safety. But what happened in Cheshire was far from a one-off. File on 4 hears from doctors with unblemished medical careers who were sacked after raising patient safety concerns. The programme follows one medic through an Employment Tribunal as he attempts to save his career, and hears the emotional, brutal toll the process takes on him. For the first time, a top doctor who won record damages talks about the extraordinary steps her managers took to undermine her. Their tactics included relocating her to an empty office with a broken chair and telling colleagues that she agreed with their assessment she was incompetent. And a former NHS executive tells the programme that trusts are more interested in “flying LGBT flags” than tackling concerns about patient safety. With widespread calls for NHS managers to be regulated, File on 4 asks who should take on the role, given the willingness of the NHS to redeploy managers found to have ignored patient safety concerns, or even punished those who dared to raise them.

Data obtained exclusively by File on 4 has revealed over the past five years at least 80 babies have died or suffered serious brain injuries in NHS maternity units in England, where interpreting and communication problems due to language difficulties, were a contributing factor. The programme also hears from an alleged victim of serious sexual abuse who says she was unable to give police an accurate account of her ordeal because the interpreter was so poor. Campaigners claim huge disparities in the levels of qualifications required in public service organisations and poor rates of pay have caused an exodus of qualified interpreters, which they claim is putting some of society's most vulnerable people at risk of harm.Reporter: Matthew Hill Producers: Ben Robinson and Surya Elango Technical Producer: Richard Hannaford Production Coordinators: Tim Fernley and Jordan King Editor: Carl Johnston

As a young person, Ellen Macleod wasn’t sure whether her disabilities would mean she could never have sex so she turned to the internet. There she found porn featuring disabled adults, but those films threw up dark questions around consent, exploitation and whether disabled people were being made the involuntary subject of a fetish. Now Ellen has teamed up with journalist Nastaran Tavakoli Far to investigate whether what she saw online was extreme role play or very real abuse. Ellen and Nas speak to disabled adult content creators, as well as safeguarding and legal experts to explore how society protects vulnerable adults, and what many of us get wrong about sex and disability.
