Its job was to look into suspicious betting activity after a game involving Nikolay Davydenko and Martin Vassallo Arguello.

Both players were cleared of violating any rules, but the investigation developed into a much wider enquiry looking into a web of gamblers linked to top-level players.

The documents we have obtained show the enquiry found betting syndicates in Russia, northern Italy and Sicily making hundreds of thousands of pounds betting on matches investigators thought to be fixed. Three of these matches were at Wimbledon.

In a confidential report for the tennis authorities in 2008, the enquiry team said 28 players involved in these matches should be investigated, but the findings were never followed up.

Tennis introduced a new anti-corruption code in 2009 but after taking legal advice were told previous corruption offences could not be pursued.

“As a result, no new investigations into any of the players who were mentioned in the 2008 report were opened,” a TIU spokesman said.

In subsequent years, there were repeated alerts sent to the TIU about a third of these players. None of them was disciplined by the TIU.

A group of whistle blowers inside tennis, who want to remain anonymous, recently passed the documents on to the BBC and Buzzfeed News.

We contacted Mark Phillips, one of the betting investigators in the 2007 enquiry, who told the BBC that they discovered repeated suspicious betting activity about a clear group.

“There was a core of about 10 players who we believed were the most common perpetrators that were at the root of the problem,” he said.

He has never spoken publicly about the material he gathered, which he said was as powerful as any he had seen in over 20 years as a betting investigator.

“The evidence was really strong,” he added. “There appeared to be a really good chance to nip it in the bud and get a strong deterrent out there to root out the main bad apples.”

The BBC and Buzzfeed were also passed the names of other current players the TIU have repeatedly been warned about by betting organisations, sports integrity units and professional gamblers.

Many of these players have been on the radar of the tennis authorities for involvement in suspicious matches going back to 2003.

The BBC and Buzzfeed News have decided not to name the players because, without access to their phone, bank and computer records, it is not possible to determine whether they may have been personally taking part in match fixing.

However, tennis’ integrity unit does have the power to demand all this evidence from any professional tennis player.

“There is an element of actually keeping things under wraps,” said Benn Gunn, a former police chief constable who conducted a major review of betting in tennis that led to the creation of the Tennis Integrity Unit.

It’s the first time he has publicly spoken about his concerns.

“If they were really serious about dealing with this, then they really need to create an integrity unit with teeth,” he said.

The European Sports Security Association, which monitors betting for leading bookmakers, flagged up more than 50 suspicious matches to the TIU in 2015.

The organisation declared that tennis attracts more suspicious gambling activity than other sport.

While he welcomed the support of the betting industry, Nigel Willerton, director of the TIU, said “it is not the role of betting companies to make judgements about corrupt activity”.

He added: “All credible information received by the TIU is analysed, assessed, and investigated by highly experienced former law-enforcement investigators.”

The problem of suspicious betting and match-fixing is not going away.

Eight of the players repeatedly flagged to the TIU over the past decade are due to play in the Australian Open which starts on Monday 18 January.

Analysis

BBC tennis correspondent Russell Fuller:

“The TIU has a full-time staff of just five and relies on intelligence from players and betting companies to alert them to potential corruption. They have a presence at between 20 and 30 tournaments a year, and their investigations over the past two years have resulted in seven players and one official being banned for between six months and a lifetime.

“Only one of those players has ever reached the top 200, and there are clearly temptations for lower-ranked professionals. Players outside the top 200 are unlikely to earn much more than £40,000 in prize money each year, and that is before coaching, travel and hotel expenses are taken into account.

“It is highly debatable whether enough resources are directed towards the TIU, and another potential flaw is that representatives from the sport’s four governing bodies decide whether the evidence gathered is strong enough to be presented to an independent hearing. Professional Tennis Integrity Officers from the ITF, ATP, WTA and the Grand Slams make that call, and as a result the process is not as transparent as it should be.”
