So many of us remember that terrible day. The absolute horror when a bomb, planted by the IRA, ripped through the Grand Hotel in Brighton during the 1984 Conservative Party Conference. It killed five people, but it also left Norman Tebbit's wife Margaret, who died at the weekend aged 86, permanently paralysed.
The abiding image of that awful morning, as we watched the emergency services rescuing people from the rubble, was seeing Tebbit, the Tories' ultimate tough guy, being carried out on a stretcher. He was barely clothed and his face was white and contorted with pain.
It was a deeply upsetting thing to see, whether you agreed with his politics or not.
