Michael Vaughan says he is "pretty sure" Australia were tampering with the ball during the recent Ashes series against England as cricket chiefs held crisis talks over the cheating scandal engulfing the sport.
Australian captain Steve Smith has been suspended for one Test and docked his entire match fee by the International Cricket Council for his role in a plot that saw teammate Cameron Bancroft tamper with the ball during the third Test against South Africa.
Smith said it was the first time time it had happened under his captaincy but Vaughan, who led England to Ashes glory in 2005, believes it has been going on for "quite a while".
"I can't believe that this hasn't happened before," Vaughan told the BBC. "I look at the amount of tape some of the fielders have worn, particularly during the Ashes series, mid-on, mid-off. (You) don't have to name names but they know who they are.
"I'm pretty sure that it was going on during the Ashes series. But it wasn't the reason why England lost 4-0. They still would have lost that series."
"One unwritten rule in the game is that you don't take a piece or an object out there to tamper with the ball, and I'm pretty sure the Australians and the players involved in that leadership group will face the consequences."
