Channel 4 has announced that a Coronation Street-themed episode of Come Dine With Me will air next month to mark the soap's 50th anniversary.

Former cast members Julie Goodyear (Bet Lynch), Ken Morley (Reg Holdsworth), Tupele Dorgu (Kelly Crabtree) and Philip Middlemiss (Des Barnes) will all feature in the special edition of the popular culinary contest.

Following the usual Celebrity Come Dine format, the foursome must compete to host the best dinner party in a bid to win a cash prize for charity.

It is thought that the one-off episode will see tension develop between the competitors after Morley's bawdy sense of humour fails to impress Dorgu.

On the second night of the competition, things get worse when Morley arrives in character as an annoying American preacher - earning him a telling-off from the actress.

Meanwhile, when it is Goodyear's turn to play hostess, she orders the male contestants to arrive in drag and causes a stir by having a scantily-clad slave named Dave serving her guests.

Come Dine With Me's Corrie special airs on December 5 on Channel 4.
