An International Tennis Federation spokesman at the Australian Open says the Tennis Integrity Unit plans to issue a statement on Monday in reaction to reports over match-fixing in the sport.

The BBC and BuzzFeed News says secret files exposed evidence of widespread suspected match-fixing at the top level of world tennis. The report said that in the last decade, 16 players who have been ranked in the top 50 have been repeatedly flagged to the integrity unit.

The reports say the players – it doesn't identify the players or say whether they were involved in singles or doubles – were allowed to continue competing.

The Tennis Integrity Unit was formed in 2008 as a joint initiative of the ITF, the ATP, the WTA and the Grand Slam Board.
