Reaction to SF's Martin McGuinness questioning the commitment of unionists to power sharing.

Are unionists committed to power sharing in Northern Ireland? Martin McGuinness doesn't seem so sure. In a speech at Sinn Fein's Ard Fheis at the weekend he took a swipe at his power sharing partners.

Having criticised dissidents, the deputy first minister said the enemy of the political process in many ways is not from outside but from within.

Sinn Fein's Gerry Kelly and the DUP's Jeffrey Donaldson give their reaction to the Deputy First Minister's comments.
