Since retiring from full-time commentary in 2001 Murray has remained involved
in the sport, an occasional presence in the paddock, and still acts as a
pundit for the BBC and F1 Racing magazine among others.

Walker, who has cancelled plans to attend the British Grand Prix next week,
will undergo a course of chemotherapy over the next few months in an attempt
to cure the disease.

News of his condition brought forth a torrent of get-well messages on social
networks, although Murray himself was typically selfless.

F1 Racing said on Twitter that he had barely mentioned his condition when
writing to tell them that they might be without his services for a short
while.

“Anyone who knows Murray Walker will not be at all surprised to learn that in
an email telling us he might be forced to miss a column or two his major
concern was that F1 Racing should find a ’Plan B’ in case chemotherapy
prevented him from filing copy!” the magazine wrote.

“Mention of his cancer diagnosis almost an afterthought.”
