BBC documentary on the police investigation that led to the capture of Patrick Magee: the man responsible for the Brighton Bomb. On 12 October 1984, Magee made an audacious attempt to kill Prime Minister Margaret Thatcher and her cabinet by exploding a bomb at the Grand Hotel in Brighton during the Conservative Party Conference. The Prime Minister was unharmed but five people were killed in the attack and many more injured.

Last August's shooting of a young Catholic, Loughlin Maginn , was the 2,744th murder since the present Northern Ireland troubles began. But it will be remembered as the killing which triggered off a damaging row between the governments of London and Dublin. Maginn was targetted and murdered by Protestant terrorists using an intelligence file leaked from within forces there to prevent such violence. Next month a report on the collusion betweenLoyalist paramilitaries and dissidents in the army and police will be delivered by a team of English detectives sent to plug the leaks. John Ware reveals disturbing new evidence that the principal source of leaks is from within the locally recruited Ulster Defence Regiment. (BBC Genome)
