Four-time Olympic champion Sir Ben Ainslie has left Sir Jim Ratcliffe's Ineos Britannia America's Cup sailing team.
Ainslie, 47, reportedly, external had a strained relationship with Manchester United co-owner Ratcliffe regarding plans for the next America's Cup which prompted the exit.
Ainslie was Ineos Britannia's team principal and skipper having joined up with Ratcliffe in 2018 in a bid to a deliver a first win for Great Britain in the yacht race since it started in 1851.
Ineos said in a statement that they could "not find agreement" with Ainslie on "terms to move forward" after last year's event in Barcelona which was won by New Zealand.
Ineos will continue to compete in the next America's Cup under the 'Britannia' name.
Ratcliffe did not address the split with Ainslie directly but said he was "enormously proud" of "developing a British boat that was truly competitive for the first time in decades".
Ainslie won medals at five consecutive Olympics from 1996 onwards, including gold at four consecutive Games from 2000 to 2012.
Since winning gold at London 2012, Ainslie's goal has been to claim the America's Cup for Great Britain but all his attempts in a British boat, including those backed by Ineos, have ended in disappointment.
