According to a report from *The Guardian*, tennis officials from the ITF and the Tennis Integrity Unit (TIU) will be asked to appear before a parliamentary committee to explain why there was no announcement about the ban of two umpires.
The parliamentary hearing had been organized following published accounts that the TIU had previously received details about match-fixing which had not led to any sanctions against players.
Tennis officials, led by ATP CEO Chris Kermode, have publicly denied suppressing or not following up properly on any indications of match-fixing received.
A British Member of Parliament on the committee for culture, media and sport, Damian Collins, told the publication that the system has to be looked at.
"The Tennis Integrity Unit is only really accountable to other people in tennis. There’s no outside scrutiny. It needs more resource and proper independent scrutiny," Collins said.
"They seem to have been in denial about the scale of the problem," he added. "Everyone in tennis knows it’s a huge problem. The TIU seems to be a Wizard of Oz type operation—they speak with great authority but behind the curtain there’s only one man."
The Tennis Integrity unit has previously announced one sanction of an umpire. The ITF was cited as saying that previous rules, now changed, did not call for public announcement of sanctions against officials.
Collins said that the revelations were a "wake up call" for a sport that has been "hopelessly under-sourced."
