LONDON (Reuters) - British billionaire Jim Ratcliffe's acquisition of a 25% stake in Manchester United was ratified by the Premier League on Tuesday after he passed the organisation's Owners' and Directors' test.

The $1.25 billion deal, in which the INEOS chairman will also invest $300 million into club infrastructure and take charge of the club's soccer operations, was struck in December but still faced hurdles, including Premier League approval.
