Turkish Purges / Republican National Convention / Nice: a city in mourning

Part one: Following Turkey's failed coup, President Erdogan has seized the opportunity to purge his political opponents. Some eighteen thousand have been arrested at last count, is Erdogan forcing his agenda or did the plot go that deep? To offer some insight, Ruadhan Mac Cormaic reports from Istanbul. Part two: "A most unconventional conventional", is how our Washington Correspondent Simon Carswell describes the 2016 Republican National Convention in Cleveland. Plagiarized speeches and Nixon comparisons are just the beginning. Part three: Lara Marlowe reports from a shell-shocked Nice. Tensions are still high with Arabs feeling scapegoated for last Thursday's Bastille day attack and support for the right-wing National Front on the increase.
