Police say IRA haven't gone way, Sinn Fein say they have. What happens next? #BBCNolan

Those are the words of Northern Ireland's most senior policeman, Chief Constable George Hamilton. But he also says the organisation is not engaged in terrorism and remains committed to politics. Yet Sinn Fein are standing firm in denial, with their president Gerry Adams declaring yesterday the IRA has "gone away".

And what way are things likely to play out? Stephen talks to journalist Brian Rowan, commentator and former Sinn Fein publicity director Danny Morrison and DUP MP Jeffrey Donaldson
