A "tsunami" of match-fixing is plaguing lower-level tennis events, says a long-awaited report into corruption in the sport.
But the Independent Review Panel (IRP) has found no evidence of a cover up of these issues by governing bodies or the Tennis Integrity Unit (TIU).
The report also shows no evidence of top-level players being implicated.
The panel - which BBC Sport understands cost close to £20m to fund - spoke to more than 100 players for the report.
Wednesday's report says there is a "very significant" corruption problem at "lower and middle levels of the sport" and especially in the men's game.
