Walker was considered the voice of the sport for a generation, having commentated on BBC’s coverage for 20 years between 1976 and 1996, part of a broadcasting career that spanned 50 years.
He also worked as a commentator for ITV when the channel gained the rights to races in 1997, until his retirement in 2001, though he continued to make occasional broadcast appearances thereafter.
His death was confirmed by the British Racing Drivers’ club on Saturday evening and prompted widespread tributes from across the sport.
“So sad to hear of Murray’s passing,” Hamilton wrote on Twitter. “I remember growing up hearing your voice over the races. You made the sport so much more exciting and captivating.
“The iconic voice of our sport and a great man, thank you for all you did, you will never be forgotten. Rest in peace.”
