Stacey Slater was tonight revealed as Archie Mitchell's murderer in a live episode of 'EastEnders'.
Actress Lacey Turner was only told 30 minutes before tonight’s live show that her character was the killer.
Stacey's confession came just after new husband Bradley fell off the roof of a building as he was chased by police.
Tension built throughout tonight's programme with characters pointing the finger at one another.
Phil Mitchell ransacked Ian's house looking for evidence, Janine confronted Peggy and Archie's daughter Roxy accused her sister Ronnie, who revealed she was sexually abused by their father.
The live broadcast apparently went smoothly, apart from Scott Maslen, who plays Jack Branning, stumbling over some lines in his opening scene.
Archie was beaten to death with the bust of Queen Victoria in the pub on Christmas Day and the identity of the killer has remained a closely guarded secret with not even the cast knowing who is the one.
Only seven people knew the true identity of the killer just hours before the live show to mark 25 years of the popular BBC soap.
Digital Spy reported that the moment when leading producer Diederick Santer informs the star would be filmed for BBC Three’s 'Eastenders Live: The Aftermath'.
The show is being presented by George Lamb, the TV presenter son of Larry Lamb who played Albert Square’s most recent villain Archie.
Writers on the soap wrote 10 possible endings with each actor rehearsing their scene, not knowing which would be chosen on the night.
