Former motorsport boss Max Mosley, who later became a privacy campaigner, has died aged 81.

Ex-Formula 1 boss Bernie Ecclestone said it was "like losing a brother".

Mr Mosley served three terms as president of motorsport's governing body the FIA from 1993 to 2009.

He also campaigned for tighter press regulation after winning £60,000 damages from the News of the World when it wrongly published a story alleging he had attended a Nazi-themed orgy.

Mr Mosley, in his role as FIA president, led widespread reforms of safety procedures in Formula 1 following the death of Ayrton Senna in 1994.

Mr Ecclestone added: "He did, a lot of good things not just for motorsport, also the [car] industry. He was very good in making sure people built cars that were safe."

Current FIA president Jean Todt said in a tweet he was "deeply saddened" by the news, adding that Mr Mosley "strongly contributed to reinforcing safety on track and on the roads".

Meanwhile, a spokesman for F1 described Mr Mosley as "a huge figure in the transition" of the sport.
