"I'm glad to say that she never forgave those who blew up the Grand Hotel," Lord Tebbit remarked.
"We all know it's a Christian duty to forgive - but not those who will not repent, and of course the people who did this have never repented; they were joyful about what they had done."
Belfast IRA man Patrick Magee was convicted of planting the killer bomb and given eight life sentences at the Old Bailey in 1986, with a recommendation that he spend at least 35 years in jail.
He was released in 1999 under the terms of the Good Friday Agreement.
