Are You Being Served? star Trevor Bannister dies at 76
The actor suffered a heart attack on Thursday at his allotment in Thames Ditton, Surrey, John Bannister said.
The actor was best known for his role as ladies' man Mr Lucas in the 1970s BBC sitcom set in a department store but he also worked in the theatre.
Frank Thornton, who appeared as Captain Peacock in Are You Being Served?, told the BBC he had "many, many happy memories" of his co-star.
"He was a very good friend over a long time," he said.
"We often met with him and his wife - he was recently at my 90th birthday celebrations in January and that was the last time we saw him. We shall miss him sorely."
Born in Durrington, Wiltshire, and the youngest of three children, Bannister did two year's National Service before going to the London Academy of Music and Dramatic Arts.
During his career which spanned five decades, he appeared in TV shows including The Avengers, Dixon of Dock Green, The Saint and Z Cars.
