Bernie Ecclestone led motorsport's tributes to the late Max Mosley, the former F1 supremo saying the passing of his old friend is "like losing family, like losing a brother".
Mosley, who died on Sunday night at the age of 81 after a long battle with cancer, was a central figure in motorsport, first as a co-founder of March Engineering and then later as the controversial president of the FIA.
But more significantly, Mosley formed for many years an inseparable double act with Ecclestone that progressively transformed F1 into a billion-dollar entertainment powerhouse.
"It’s like losing family, like losing a brother, Max and I," said a saddened Ecclestone. "He did a lot of good things not just for motor sport, but also the [car] industry.
"He was one of the greatest people I ever knew. He should have been Prime Minister and I told Margaret Thatcher that.
"He suffered for too long," said Ecclestone of Mosley's terminal illness.
Current FIA president Jean Todt also made tribute to Mosley achievements and legacy at the helm of motorsport's governing body.
"Deeply saddened by the passing of Max Mosley," Todt wrote on Twitter.
"He was a major figure in F1 & motor sport. As FIA President for 16 years, he strongly contributed to reinforcing safety on track & on the roads. The entire FIA community pays tribute to him. Our thoughts & prayers are with his family."
