Undercover British army units in the North celebrated the killing of IRA members with cakes carrying the names of their victims, according to a BBC programme.
Brits, a series made by award-winning journalist Peter Taylor which will be screened tonight, claims members of the 14th Military Intelligence Company had cakes baked in the shape of a cross with the names of IRA members shot dead.
Mr Taylor released a photograph of a cake bearing the name of Mr William Price (28) from Ardboe, Co Tyrone. He was shot dead by the SAS in 1984 as he helped plan an attack on a nearby factory.
The programme claims a report to the British government suggested MI5 officers had perverted the course of justice. It claims the report alleged they destroyed a tape which would have disclosed whether Mr Michael Tighe (17) - who was shot dead near Lurgan in 1982 - had been warned that he and a friend, Mr Martin McCauley, were under observation and could have been shot.
Also interviewed is a corporal in the Parachute Regiment who arrived at the scene of the shooting of Ms Bernadette McAliskey and her husband Michael in Coalisland, Co Tyrone, in 1981. He said he believed the SAS allowed the attempted murders to go ahead. He claimed when he asked why the loyalists had been allowed to bring down the McAliskeys' telephone line and smash in their door, he was told: "We must have been looking the other way."
