From Sunningdale to St Andrews: a long, winding and bloody road

SO, is the St Andrews Agreement a new deal or an old one, a rehash of everything that has gone before or something entirely innovative and different? Does it matter?

Surely what matters now is the possibility that finally, after nearly 40 years of howling at each other, the extremes of Northern politics have finally, it seems, found a way to begin working together.

I can remember being in the Irish delegation that went to Hillsborough Castle in 1985 to sign the Anglo-Irish Agreement.
