Lehmann was Australia's head coach when the ball-tampering scandal took place in 2018.
David Warner has publicly backed former ICC match referee Chris Broad in calling out ex-Australia coach Darren Lehmann for hypocrisy over the 2018 "Sandpapergate" scandal.
Responding on social media to Broad’s remarks, Warner wrote that he "couldn't agree more" with the criticism, indirectly supporting the view that Lehmann knew about the ball-tampering plot in Cape Town.
Speaking on Track Radio, Broad stated that Lehmann "surely knew all about" the sandpaper plan and argued he "got away lightly" by resigning without formal sanctions.
Broad contrasted Lehmann's denial of the 2018 plot with his 2013 Ashes tirade, when the latter called the former’s son, Stuart Broad, a "blatant cheat" for not walking after edging a ball and vowed Australian fans would make him "cry".
“I am very angry at Lehmann. Lehmann surely knew all about it (ball tampering) and if he did not, he should not have been the coach at the time. And I think he has got away lightly because, OK, he left his job a few months later, but he did not get any sanctions," Stuart’s father, Chris Broad, said in an interview.
“And there he was in 2013, taking the moral high ground against my son, where he played the Australian game of nicking the ball and waiting for the umpire to give him out… and then came out in the media saying ‘we are going to make him cry when he comes to Australia next," Chris added.
Taking to X, Warner commented on a post sharing Broad’s comments, stating: "I couldn't agree more and that's hard for me to say!"
This rare agreement with Stuart Broad's father serves as a direct swipe at Lehmann, who has long maintained he was unaware of the plan.
The controversy resurfaced following revelations in Usman Khawaja's autobiography, Sabr, in which he rejected the long-held assertion that only Steven Smith, Warner, and Cameron Bancroft were involved in the scandal.
Khawaja claimed that the entire touring party was aware of the ball-tampering plot and that the Australian team had successfully used sandpaper on the ball a game prior to the infamous Cape Town Test.
Warner endorsed Khawaja's account as "100% accurate" and called the original 2018 Cricket Australia integrity investigation a "rushed and botched" process.
Meanwhile, Cricket Australia chief Todd Greenberg has ruled out reopening the investigation, stating there is no compelling reason to revisit the case.
