Whatever your politics or point of view, the sheer idea of the two of them agreeing to anything, let alone power sharing, would have been unthinkable a year ago. If you had said it to anyone from the north 10 years ago they would have laughed at you. 20 years ago and they might have thought you weree taking the piss and bbeaten you to a pulp.

This is the unthinkable happening, and of immeasurable significance.

But that's the story of most peoples lives - so many unthinkable things have happened in mine that I become uneasy during the calm.

Well done Gerry and well done Ian - for them the right thing was hardest to do.
