Q&A: The murder of Pat Finucane
The UK government is due to publish a review of the murder of Belfast solicitor Pat Finucane.
His death was one of the most controversial killings during the Troubles - the decades of conflict in Northern Ireland that claimed the lives of more than 3,000 people.
Who was Pat Finucane?
Pat Finucane was a high-profile solicitor who lived and worked in Belfast. The 39-year-old Catholic was shot dead by loyalist paramilitaries in 1989.
In his role as a defence solicitor, he had represented clients who included convicted members of the Irish Republican Army (IRA) and families involved in shoot-to-kill allegations against the then police force, the Royal Ulster Constabulary (RUC).
There have been long-standing allegations that members of the UK security forces colluded in his murder.
How was he killed?
Pat Finucane was shot in front of his wife and three children at their family home in north Belfast on 12 February 1989.
The family were eating a Sunday meal at their kitchen table when loyalist paramilitaries used a sledgehammer to break into their house.
They opened fire, shooting the solicitor 14 times. He died at the scene.
Mr Finucane's now adult son, Michael, later wrote that the image of the attack had been "seared" into his mind. "The thing I remember most vividly is the noise; the reports of each bullet reverberating in the kitchen, how my grip on my younger brother and sister tightened with every shot," he recalled.
The Ulster Freedom Fighters (UFF), a loyalist paramilitary group with links to the Ulster Defence Association (UDA), later admitted carrying out the murder.
The UFF claimed they had killed "Pat Finucane, the IRA officer".
The solicitor's family have always vehemently rejected any claim that Mr Finucane had been a member of the IRA, and have been supported in this by the police.
Why is the case so controversial?
In the course of his work, Pat Finucane had represented a number of high-profile IRA prisoners, some of whom had taken part in hunger strikes at the Maze Prison.
The year before he died he had defended former IRA hunger striker Pat McGeown, who had been charged with helping to organise the murder of two Army corporals who drove into an IRA funeral cortege in west Belfast.
The mourners dragged the corporals from their car and took them to waste ground where they were shot dead by IRA gunmen.
The abduction was captured on TV and remains among the most disturbing images of the Troubles.
Mr Finucane succeeded in getting the charges against his client dropped, but it is claimed a double agent passed a photograph of the solicitor, taken outside the court, to the UFF gunman who carried out his murder.
The double agent was Brian Nelson, who compiled information on potential targets for the UFF, while at the same time working for British Army intelligence.
Has anyone been convicted of the murder?
In June 1999, a former UDA quartermaster and ex-RUC Special Branch agent, William Stobie, was charged with murdering Mr Finucane.
Stobie admitted supplying the guns used in the killing but denied murder.
Just over two years later, the case against him collapsed due to the refusal of a key witness to give evidence.
Stobie walked free from court but within weeks had been shot dead outside his own home by loyalist gunmen.
In May 2003, the loyalist Ken Barrett was arrested and charged with the murder of Mr Finucane.
Barrett later confessed in court to killing Mr Finucane and was sentenced to 22 years' imprisonment in September 2004.
What is the purpose of Wednesday's review?
The de Silva report is not a new inquiry but rather a review of all the existing documentation on the Finucane murder.
Why have the Finucane family refused to support the review?
The Finucane family have campaigned for a full public inquiry into the murder for many years and have repeatedly insisted that they will not accept anything less.
The Finucanes believe that a public inquiry, where the veracity of documents and witnesses can be tested under cross-examination, is the best way of getting to the truth about the extent of security force collusion and exactly who knew what.
