Motor racing: Button's father, popular F1 figure, dies of suspected heart attack
LONDON (REUTERS) - John Button, father of 2009 world champion Jenson and a popular presence in the Formula One paddock, has died of a suspected heart attack aged 70.
The McLaren driver's agent said in a statement that the body was found at home in the south of France by a friend on Sunday.
McLaren team principal Martin Whitmarsh mourned a "unique and...irreplaceable part of the McLaren family" while drivers and bosses paid fond tributes to the Briton.
"In my long Formula One career, I've encountered many drivers' fathers, but I think it's safe to say that John was perhaps more devoted to his son than any of them," said Whitmarsh.
