'Enders boss reveals Lacey killer reaction

Departing EastEnders boss Diederick Santer has revealed how Lacey Turner reacted when he told her that Stacey Branning was Archie Mitchell's killer.

Santer only informed Turner of her alter ego's secret minutes before the programme's live 25th anniversary episode went to air on Friday night.

The actress's reaction to the news was originally intended to be filmed for broadcast on EastEnders Live: The Aftermath, which aired on BBC Three after the special instalment.

However, Santer this afternoon told Richard Bacon on 5Live: "Lacey came to see me and I had a camera pointed at her [to record] the whole thing, but because I'm technically incompetent I didn't actually press record!

"I said, 'Lacey, I think you may have worked out why you're here - Stacey killed Archie. It was you!'

"Then she said something I can't really repeat right now, but she went with it. She started asking questions about the ending and about the performance."

The show's executive producer also confessed that he felt nervous and started chewing his pen when Scott Maslen (Jack Branning) fluffed his lines in one of the live episode's early scenes.

However, he added: "What [was] wonderful [was] his recovery. It happened within the first few minutes and [then] he was exemplary for the rest of the episode. He's done two live episodes of The Bill and he's a rock-steady kind of guy so I knew he'd pull it back."
