US sports tycoon Malcolm Glazer has increased his stake in Manchester United, buying a further 4.1 million Manchester United shares,to take his shareholding from 16.69% to 18.25%.

Glazer has been increasing his share over the last few months, but on last month he issued a statement denying he was preparing a takeover bid.

However this latest share purchase will renew speculation that he is preparing a bid for the club. Mr Glazer said he had “no current intention” of launching a takeover bid for the club. However he added that he might “consider increasing or decreasing its shareholding in Manchester United in the future.”

Mr Glazer owns Tampa Bay Buccaneers American football team.

The largest single shareholders in Man United are Irish businessmen John Magnier and JP McManus, who own 28.89% of the club.
