The widow of murdered Belfast Catholic solicitor Pat Finucane has made a fresh call for an independent inquiry into her husband's death following fresh allegations of security force obstruction of the murder investigation.
Mr Finucane was shot dead in front of his family in their north Belfast home in 1989 by the loyalist Ulster Freedom Fighters.
There have been continuing claims of security force collusion and the murder is subject of an ongoing investigation by a team headed by Sir John Stevens, Commissioner of the Metropolitan Police.
Mrs Geraldine Finucane restated her continuing calls for an independent inquiry following claims by an ex-detective in the RUC that the Special Branch blocked the efforts to jail the killers of Mr Finucane.
Mr Johnston Brown told a UTV programme last night that in 1991 he taped a loyalist outlining his involvement in the murder of the Belfast lawyer.
But he said the admission was never fully investigated and the force's intelligence-gathering arm obstructed his attempts to reveal details to the Stevens Inquiry.
Mr Brown said: "Someone, within a week of that confession being in our domain, had made the decision not only not to go forward with the investigation - but to obstruct and to ensure that anyone like myself coming forward would be ridiculed."
The Northern Ireland Police Ombudsman Ms Nuala O'Loan has sent for a transcript of Mr Brown's interview in order to decide whether she should launch her own formal investigation.
Mrs Finucane said it was now "extremely obvious" that the only way to get at the truth was through an independent inquiry.
The Finucane family have enlisted the backing of the Government and have gone to Downing Street and Europe in their long running campaign for an inquiry into the murder.
