The British Parliament’s Culture, Media and Sport Committee has announced its terms of review for an inquiry into match-fixing in tennis, and will be calling officials to testify this week.

Three officials are to appear: Tennis Integrity Unit chief Nigel Willerton, ATP CEO Chris Kermode, and ATP legal counsel Mark Young.

In addition, it also gave the terms of its inquiry. The first are allegations "that sport’s governing bodies have been warned repeatedly about a core group of 16 players—all of whom rank in the top 50—but none has faced any sanctions and more than half of them played at the Australian Open."

These refer to the joint BBC investigation into match-fixing published during the Australian Open, which is specifically referenced by the committee.

The committee will also investigate claims that tennis governing organizations were "told by Betfair and other bookmakers of the threat of gambling corruption in tennis over a period of several years."

In general, it aims to look at efforts in tennis to stop match-fixing, and any problems to be addressed.

No ITF or WTA officials have been called in what is described as a "one-off" hearing, though that does not preclude other sessions.

More recently, a story in The Guardian said two umpires had received unannounced bans and four others were under investigation for breaching anti-corruption rules, including delays in entering match scores and providing advance notification of scoring to gamblers. The ITF confirmed the bans and the investigations.

The committee had indicated that it would also look at The Guardian's allegations, but it did not specifically refer to them in the issues to be addressed.
