EastEnders boss Dominic Treadwell-Collins has opened up about Peggy Mitchell's upcoming exit from the soap.
The exec producer, who was appearing alongside Lacey Turner on The One Show, said that celebrated writer Sarah Phelps is also returning to pen Barbara Windsor's final episode as Peggy.
Speaking about Peggy's departure, Treadwell-Collins said: "We haven't filmed [it] yet. The scripts are coming in, we've got Sarah Phelps [who] has come back to the show.
"She wrote The Casual Vacancy… she's coming back to write Barbara Windsor's last episode."
When asked how the show got Ross Kemp to return, Treadwell-Collins explained: "Well I think [with] Barbara leaving, he had no choice.
"I've had a lot of dinners with him trying to woo him to get him to come back, but he's so busy.
"And then finally, the stars have aligned… everyone at work's very excited about it."
He added: "It's gonna be epic. It's got to be epic… everyone's got such high expectations for it."
Phelps is returning to the show despite hitting out at EastEnders for the retconning of the famous "hello princess" line that she wrote on Dirty Den's return in 2003.
