Ms McAllister was speaking after Northern Ireland Secretary of State Hilary Benn announced the establishment of an independent inquiry into the murder of Belfast solicitor Pat Finucane.

“A public inquiry was always necessary in this case, given the serious public interest issues involved and the UK Government’s acceptance that collusion played a part,” she said.

“I hope it takes place in line with the requirement for an independent investigation under Article 2 of the European Convention of Human Rights. The Supreme Court has stated previous investigations had not been effective, so it now comes down to this inquiry for the truth to be unveiled. As such, I hope we receive clarity soon in terms of its ability to compel witnesses and evidence.

“I pay tribute to the Finucane family, who have held a dignified campaign over the years. I hope this announcement brings them some comfort and the eventual findings of the inquiry do likewise. All of those who suffered tragedy during the Troubles deserve justice for their losses.

“This once again shines a light on the pressing need for a sensitive, all-encompassing government strategy on dealing with our troubled past. The Secretary of State must outline urgently how the detested Legacy Act will be repealed and replaced.”
