Stakeknife: IRA's most senior double agent to be quizzed about 24 murders
The IRA's most senior double agent is to be investigated about the murder of at least 24 people.
The army agent, who was given the codename Stakeknife, has been named by the BBC as west Belfast man Fred Scappaticci. He has denied he was an agent.
Northern Ireland's director of public prosecutions wants the new investigation to look at what information the army, MI5 and the Royal Ulster Constabulary's Special Branch received from Stakeknife.
So... what are the odds of this investigation telling us things we don't know about murders by agents of the British state?
