Litten announced on his Twitter page that work on his new project had started but refused to reveal too many details.
"Yesterday I had a brand new TV show commissioned!" he said. "Can't say what it's about, can't say which channel, can't say anything yet... Just celebrating with a pint of Ribena! What a crazy bitch I am."
However, Litten did joke that the new show will differ from Benidorm in one important way.
He said: "One thing I will say about my new comedy... It's not set in Spain!"
Benidorm was renewed for a fifth series by ITV in April. Litten had previously suggested that he would leave the show but has agreed to return to write some of the new episodes.
