Diane Morgan has revealed she is writing a sitcom in which she and Maxine Peake play "wildly different sisters".

Speaking to Radio Times backstage at the magazine's Covers Party, the comedy star confirmed she was currently working on a script.

Morgan and Peake have been best friends since childhood and have recently appeared together on Gold's Gogglebox-style series We Have Been Watching (pictured). Morgan also reportedly has a role in Funny Cow, a forthcoming comedy film in which Peake plays a female comedian working the northern working mens' club circuit in the 1970s and 1980s.

Morgan's currently un-titled sitcom project is still at the development stage, and no broadcaster is yet attached. She said in a video interview with the magazine: "I'm writing a sitcom for me and Maxine... it might go nowhere", adding: "We're sisters, not identical obviously, that would involve a lot of prosthetics".

Speaking more about the characters, she revealed: "One of them is slightly uncouth; one of them is a big famous actress... we've sort of used real life there."

Diane Morgan also confirmed, following her role in the pilot, she would be appearing in the forthcoming series of BBC sitcom Motherland. She revealed the show's writers have finished the storylines and are now working on scripts, with filming set to start in June.

She also said she hopes to make more Cunk On... specials featuring Philomena Cunk, the character she developed via Charlie Brooker's Weekly Wipe. Suggestions for topics the fictional presenter could tackle next include punk music, modern art and Jane Austen.
