Leave and Remain MPs head to head on the Sunday Politicspublished at 11:43 British Summer Time 12 June 2016
Remain and Leave supporters get to cross-examine each other on the Sunday Politics.
Labour Remain campaigner Mary Creagh asks Chris Grayling which workers' rights he would scrap if the UK left the EU.
The Conservative Leave campaigner insists the UK has "always been better" than the EU on workers' rights.
Ms Creagh then argues that the UK trades more with the Republic Ireland than with the whole of the Commonwealth put together, yet leaving the EU would mean ending free movement over the border with Northern Ireland.
Chris Grayling rejects this claim, telling Ms Creagh there has been a common travel area between the UK and Ireland and there is "no reason for that to change".
