As well as voicing Parker for the futuristic children’s puppet series Thunderbirds, he also played the show’s pilot Gordon Tracy, and Brains the engineer, betwen 1965 and 1966.
He reprised the role of Parker for an ITV remake of the show in 2015, called Thunderbirds Are Go! and was the only original cast member to return.
Parker, famous for saying “Yes m’lady”, worked for Lady Penelope, who was played in the more recent version by Saltburn star and ex-Bond actress Rosamund Pike.
Graham said at the time: “I am triple chuffed to be on board the new series… and reprising my role of dear old Parker with such a distinguished cast.
“My driving skills are in good nick and I am delighted to be behind the wheel again with m’lady.”
He told The Mirror that the show’s creator, Gerry Anderson, had helped with the inspiration for Parker’s voice back in the 1960s.
“Gerry took me to lunch because he wanted me to hear the voice of somebody, a wine waiter,” the actor said.
“He had been a butler to the former Prince of Wales.
“He said, ‘Would you like to see the wine list sir?’ and that was the birth of Parker.
“I just made him a bit more villainous. I’m not sure the guy ever knew – he might have demanded a royalty!”
