The Prime Minister said today's report provides "the fullest possible account of the murder of Pat Finucane and the extent of state collusion".
Mr Cameron added the report found no overarching state conspiracy, but "shocking" levels of state collusion and that actions by employees of the state "actively facilitated" the killing.
The family of Pat Finucane labelled today's review into his murder is a 'whitewash' despite 'shocking' levels of state collusion revealed.
A government-commissioned report found state agents were involved in the murder of Pat Finucane - but his widow dismissed it as a "sham".
The review into the death of a Catholic solicitor during the Troubles is expected to show state collusion with loyalist terrorists.
