Only Fools And Horses star John Challis has died from cancer at the age of 79, his family has said.

Best-known for his role as the unscrupulous second-hand car dealer Boycie in the beloved sitcom, Challis grew up in south east London and Epsom in Surrey.

He cancelled a 30-date speaking tour earlier this month after only one appearance due to ill health.

A statement from his family to the PA news agency said: "It is with heavy hearts that we bring you such sad news.

"Our dear friend and yours, John Challis, has died peacefully in his sleep, after a long battle with cancer.

"He will always be loved for being 'Boycie' and leaves a great legacy of work that will continue to bring pleasure and smiles for many years to come.

"Please respect the privacy of John's family and friends at this difficult time, and be assured that in the future there will be an occasion to celebrate John's life - when everyone will be welcome to come along."

Boycie, a cigar-smoking businessman with a mocking laugh, was married to the feisty Marlene - played by Sue Holderness - and regularly butted heads with Sir David's Del Boy.

Holderness said in a statement: "Marlene without Boycie - it's unthinkable. John Challis was my partner on screen and stage for 36 years and my beloved friend. R.I.P. darling John. I will miss you every day."

Challis was born in Bristol but moved to south-east London when he was one, and later moved to Epsom in Surrey.

He attended the state boarding Ottershaw School near Woking, Surrey, and worked as a trainee estate agent before becoming a professional actor.

Early roles included gangster drama Big Breadwinner Hog in 1969 and a recurring role on Z-Cars as Sergeant Culshaw between 1971 and 1975.

Starring alongside Sir David Jason and Nicholas Lyndhurst, Challis played Terrance Aubrey Boyce in Only Fools And Horses from 1981 to 2003, as well as in Boycie-focused spin-off show The Green Green Grass.

He recently became an honorary citizen of Serbia, where the BBC sitcom remains hugely popular.

Challis made the documentary Boycie In Belgrade, exploring why the show was so beloved in the Balkan country.

He was also known for playing Monty Staines in ITV sitcom Benidorm.

Challis performed on the stage with the Royal Shakespeare Company and the National Theatre, and regularly appeared in pantomime productions.

His family have requested that instead of flowers, donations are made to his favoured animal charities - Cuan Wildlife Rescue, Tusk and The British Hedgehog Preservation Society.

Their statement added: "As Boycie would have said... you know it makes sense!"
