Jenson Button's father, John, died on Sunday after suffering a suspected heart attack.
John, who is often seen at grands prix supporting his son and who had his own career in rallycross, was found at his home in the French Riviera on Sunday. He was 70.
"It is with great sadness and regret that I can confirm John Button passed away at his home in the South of France on Sunday," a statement from Button's agent read.
"Whilst we await confirmation, initial signs would indicate a suspected heart attack. A close friend who was visiting John on Sunday was the first to discover the tragic news.
"John's children Jenson, Natasha, Samantha and Tanya and the rest of the family are clearly devastated and ask for their privacy to be respected during this extremely difficult time."
