A long-awaited tennis corruption report is not expected to find that evidence of match-fixing has been suppressed.
The Independent Review Panel (IRP) was set up in January 2016 after a BBC and BuzzFeed News investigation uncovered suspected illegal betting.
The panel - which BBC Sport understands has cost close to £20m to fund - has interviewed more than 100 individuals from across the sport.
The report will be published on Wednesday.
Betting operators, gambling regulators, data supply companies and law enforcement agencies were also questioned as part of the review.
And although this interim report is not expected to uncover evidence of corruption at the elite level of the sport, the IRP is understood to have been at least exploring some radical ideas.
