Olly Alexander and It's A Sin cast set for Great British Bake Off Christmas special

The cast of 'It's A Sin' have reunited for a Christmas special of 'The Great British Bake Off'.

Over the festive season, judges Paul Hollywood and Prue Leith will be tasting some treats from the Channel 4 series stars Olly Alexander (Ritchie Tozer), Lydia West (Jill Baxter), Nathaniel Curtis (Ash Mukherjee) and Shaun Dooley (Clive Tozer).

In an announcement on the show's official Twitter account, the team said: "On your marks, get set… La! We’re turning our Tent into the Pink Palace as the stars of award-winning @Channel4 drama It’s A Sin don their aprons for The Great Christmas Bake Off!

"Christmas tree Line-up: Olly Alexander, Lydia West, Nathaniel Curtis, Shaun Dooley Date: To be revealed!"

Hosts Noel Fielding and Matt Lucas will be back for the Christmas edition, as well as a New Year's special featuring four former bakers.

As well as series nine stars Kim-Joy Hewlett and Jon Jenkins, series 11 favourites Rowan Williams and Hermine will be back in the tent.

'It's A Sin' - which was created by 'Doctor Who' showrunner Russell T Davies - focuses on the HIV/AIDS pandemic and its impact on the LGBTQ+ community in London in the 1980s.

The show was a huge hit, and Nathaniel previously said: "None of us expected it. I was speaking to someone yesterday, and they said, 'The show is a movement.' I was like, 'What? OK.' That's fantastic.

"We're glad that our work can mean so much to people, and that it's been able to open conversations, and it's given people this pride, this yearning to learn more about what happened, and what can be done."

Although fans might want more episodes in the future, the 'Bake Off' special will be the only chance to see the whole cast back together as Russell has dismissed the idea of a second season.

He explained: "It was lovely. It said everything I wanted to say."
