INEOS Britannia has announced it is parting ways with CEO and skipper Ben Ainslie for the 38th edition of the premier yachting race.

Britain's America's Cup skipper Ben Ainslie said he was astounded at being dropped by INEOS Britannia after failing to win the trophy last year.

Sir Jim Ratcliffe has split with his America's Cup partner Sir Ben Ainslie and revealed he intends to win the race without the British Olympic legend.
