The manager of Australian cricketer David Warner has alleged that officials from Cricket Australia (CA) gave players permission to tamper with the ball more than one year prior to the eruption of the scandal in Cape Town in 2018.

Warner and Steve Smith accepted 12-month suspensions by CA for their roles in a plot to tamper with the ball during the third day of a Test match against South Africa in Cape Town, while Cameron Bancroft was banned for nine months.

Former captain Warner, who was vice-captain to Smith during the Test in question, was singled out as the orchestrator of the scheme.

He was banned from any leadership role within the team for the rest of his career, withdrawing an appeal against this yesterday after accusing an independent panel tasked with reviewing the punishment of wanting to "conduct a public lynching".

Warner's manager James Erskine has now claimed that Australia's players were granted permission to tamper with the ball after losing a Test to South Africa in Hobart in late 2016.

Australia were bowled out for 85 in the first innings of that match, although South Africa's Faf du Plessis was later found guilty of ball-tampering.

Erskine suggested that senior CA officials approved plans to tamper with the ball.

"Two senior executives were in the changing room in Hobart and basically were berating the team for losing against South Africa," he told SEN.

"Warner said: 'We've got to reverse-swing the ball.

"'The only way we can reverse-swing the ball is by tampering with it.'

"And they were told to do it."

Erskine also claimed that Warner had been "completely villainised", and "there was far more than three people involved in this thing".

He described the scandal's fallout as "injustice at its greatest level".

CA is yet to respond to Erskine's allegations.

The scandal led to the resignation of Australian coach Darren Lehmann, although he was cleared of any involvement.

CA's chief executive James Sutherland also left his role in the aftermath.

An internal review found that CA was "partly to blame" for the ball-tampering scandal.

The report found players were often subject to "bully tactics or worse, ostracising" by the organisation.
