Michael Buerk chairs a debate on the moral questions behind the week's news. Michael Portillo, Melanie Phillips, Clifford Longley and Matthew Taylor cross-examine witnesses.

It's the 25th anniversary of the Brighton Bomb and the man who planted it will be sharing a platform in Parliament with the daughter of one of the people he killed - talking about forgiveness.
