The level of state collusion uncovered by a report into the murder of Belfast solicitor Pat Finucane is "shocking", Prime Minister David Cameron has said.
However, it concluded that there was "no overarching state conspiracy".
Sir Desmond de Silva's review confirmed that agents of the state were involved in the 1989 killing and that it should have been prevented.
Mr Finucane's widow, Geraldine, has dismissed the report as a "sham" and a "whitewash".
Mr Finucane was shot dead by loyalists in front of his wife and children at his north Belfast home.
