Leyton Orient majority stakeholder Barry Hearn has completed his sale of the League One club to Italian businessman Francesco Becchetti.
Hearn, who made his fortune promoting boxing, darts and snooker among other sports, took over Orient in the 1994-1995 season.
However, following a frustrating campaign in which the O's lost in the playoff final and failed in their bid to secure the Olympic Stadium as their new home ground, Hearn has now sold his Matchroom Sport Ltd's 90% stake to Becchetti.
Becchetti, 47, becomes the new chairman at Brisbane Road, while Hearn and son Eddie, Steve Dawson and David Dodd have all resigned from the club's board, with chief executive Matthew Porter staying on as a director.
Becchetti, who is the head of the Becchetti Energy Group, had previously been linked to takeovers of Championship outfit Reading and Italian club Bologna.
