McGuinness to give Warrington peace lecture

Twenty years ago, a bomb planted in Warrington by the IRA killed two young boys and injured 54 other people.
Colin Parry, whose son Tim was one of those killed, set up a Peace Centre in the town in his memory.
Now he has invited Northern Ireland Deputy First Minister Martin McGuiness to deliver a peace lecture there to mark the 20th anniversary of the atrocity.
