The family of Mr Pat Finucane is to seek a meeting with the British Prime Minister, Mr Tony Blair, to demand a reversal of his government's decision to delay the establishment of a public inquiry into Mr Finucane's killing.
Mr Michael Finucane, a son of the murdered solicitor, said the decision to reject Judge Peter Cory's recommendation to immediately establish a judicial inquiry appeared to have been made at the highest level of the British government.
"I am not inclined to believe this is Paul Murphy's doing," Mr Finucane said in reference to the Northern Secretary who published the Cory report.
The family received unlikely support yesterday from a number of former members of the British army's Force Research Unit who, in a statement through their London solicitors, said the government should establish a public inquiry to allow them clear their names of allegations of collusion.
"It is quite extraordinary that a decision has been made not to have the public inquiry, which the solders wanted, in order to avoid prejudicing a current trial, and yet to put into the public domain material which must be highly prejudicial to that case," the statement said.
But in a separate development the PSNI Chief Constable, Mr Hugh Orde, warned that confidence in the police force was in danger of being undermined by a spate of new inquiries.
And the Ulster Unionist peer, Lord Maginnis, said the Cory report was inaccurate in alleging widespread collusion. "If there had been collusion in a wide sense the Gerry Adamses and the Martin McGuinnesses would not be alive today," he said in a statement.
Publishing the Cory report, Mr Murphy confirmed that public inquiries would be established into the murders of Mrs Rosemary Nelson, Mr Robert Hamill and Mr Billy Wright. But, he said, an inquiry into Mr Finucane's murder was pending the outcome of criminal proceedings against a loyalist, Mr Ken Barrett, who was currently in custody.
Judge Cory called for all four inquiries to begin as soon as possible. On the Finucane case he said: "This may be one of the rare situations where a public inquiry will be of greater benefit to a community than prosecutions."
As well as seeking a meeting with Mr Blair, the Finucane family plans to speak directly to the Government, which it hopes will push for an inquiry in the UK through diplomatic channels.
In addition, Mr Finucane's widow, Geraldine, is to press ahead with a High Court action in Belfast seeking to compel the British government to establish the independent inquiry in line with Judge Cory's advice.
Meanwhile the Ulster Unionist leader, Mr David Trimble, has refused to retract allegations against Mr Finucane and Mrs Nelson which have been strongly condemned by the families of the two solicitors, nationalist politicians and the Northern Ireland Law Society.
Mr Trimble, who in the House of Commons on Thursday suggested both solicitors had "a clear terrorist connection", stood over his comments yesterday, claiming that offence to the families was unavoidable.
"I don't think anybody thought he /[Mr Finucane]/ was simply a lawyer," Mr Trimble told the BBC. "I'm not saying he was /[an IRA member]/. I'm just saying there's very clear evidence of a close relationship."
Mr Eunan Magee, the brother of Mrs Nelson, challenged Mr Trimble to produce evidence to support his claims. "Whenever the inquiry into Rosemary's death takes place, it is up to David Trimble to put his evidence on the table. But I have to say it beggars belief that a member of the legal profession can make outrageous comments like these," said Mr Magee.
"I suspect this is a case of David Trimble fishing for a more hardline blue vote. Unfortunately it is the type of view that was also prevalent in all levels of the Royal Ulster Constabulary before her death."
The SDLP leader, Mr Mark Durkan, also called on Mr Trimble to withdraw the allegations, describing them as "deeply offensive".
Ms Bairbre de Brún of Sinn Féin said Mr Trimble's "dishonest and insulting" remarks were aimed at providing political cover for murders carried out by "British securocrats".
In his report, Judge Cory cited no evidence of either Ms Nelson or Mr Finucane being members of the IRA.
