A GROUP of politicians in the US has written to Boris Johnston calling for an independent, judicial investigation into the murder of Pat Finucane.
The 39-year-old solicitor was shot dead by the UDA at his family home in north Belfast in 1989.
In 2012, former Prime Minister David Cameron apologised after a report by Desmond de Silva found there was collusion in the case.
In February last year the UK Supreme Court ruled that investigations into the killing of the solicitor have not been effective and fell short of international human rights standards.
Secretary of State Brandon Lewis is due to make a decision on how the British government will proceed before the end of this month.
Now a letter signed by 24 members of the US congress has been sent to Mr Johnston urging him to order a proper investigation.
Republican congressman Chris Smith said: "The British government's deliberate decision not to proceed with an independent, judicial inquiry into the Finucane murder - an unfulfilled commitment of the peace process - is a public breach of faith."
Democrat Richard Neal, who is chairman of the bipartisan Friends of Ireland Caucus in the US Congress, said the Fincuane family "has a right to truth and justice".
"They deserve to know what happened in February of 1989 and the level of state collusion into the murder of their husband and father," he said.
"This letter is calling on the British government to be accountable."
Mr Finucane's son, Sinn Féin MP John Finucane, last night welcomed the letter.
