At 2.45am on the 12 October 1984 the Grand Hotel in Brighton was devastated by a bomb blast. The hotel was playing host to members of the Cabinet who were staying there for the Conservative party conference.
Five people died and 34 others were injured.
IRA member Patrick Magee, who had planted the bomb was sentenced to 35 years in 1986, but 13 years later he was released under the Good Friday Agreement.
Lord Tebbit, whose wife was paralysed in the bombing, has called for an inquiry into the bombing after the Saville Report into the Bloody Sunday shootings was heavily critical of the Army and found that soldiers fired the first shot.
