Dale Cregan has dramatically altered his plea to admit the murder of two police officers.
The one-eyed 29-year-old, who now faces life in jail, admitted gunning down Pcs Nicola Hughes and Fiona Bone on September 18 last year.
The court was shown CCTV of the moment Cregan handed himself in at Hyde police station, just minutes after murdering the two officers.
He is still on trial for the murders of father and son, David and Mark Short, which he denies.
Cregan lured the officers with a bogus police call before using a Glock handgun and a military fragmentation grenade to kill the unarmed and unsuspecting Pcs in Hattersley, Greater Manchester.
Cregan had initially pleaded not guilty to murdering Pc Bone, 32, and Pc Hughes, 23, at the start of his trial last week at Preston Crown Court.
The dramatic change of plea came on the fourth day of the trial.
Following the lunch adjournment the jury was brought back into court and trial judge Mr Justice Holroyde told the court there was about to be a "step in proceedings".
Simon Csoka QC, defending Cregan, got to his feet to address the judge, saying: "The defendant would like to be arraigned again on counts 10 and 11."
At 2.23pm Cregan stood up and replied "guilty" when asked to enter his new plea to the charges, read by the clerk of the court.
