The ex-wife of an IRA informer has launched a legal bid to gain full access to military documents as part of a major lawsuit involving a man alleged to have been the highest-ranking British agent within the Provisionals.
Lawyers for Margaret Keeley challenged attempts by the Ministry of Defence to secure a Public Interest Immunity (PII) certificate in the High Court.
Mrs Keeley's former husband is Peter Keeley, the one-time MI5 agent who also uses the pseudonym Kevin Fulton.
She is suing the Chief Constable, MoD and Freddie Scappaticci, the 68-year-old west Belfast man who denies allegations that he was the military spy inside the IRA codenamed Stakeknife.
The Newry woman alleges she was wrongfully arrested and falsely imprisoned during a three-day period in 1994 following an IRA attempt to murder a senior detective in east Belfast.
She believes her detention was part of an elaborate sham to protect her husband's cover. Mrs Keeley was released without charge, but claims to have then been interrogated by an IRA security team.
