Andrew McDonald will take temporary charge of the men's team

The announcement was made via a statement from Langer's management company DSEG on Saturday, the morning after a lengthy CA board meeting had finished without a resolution, while Langer was flying from Melbourne to Perth.

"DSEG confirms that our client Justin Langer has this morning tendered his resignation as of the Australian men's cricket team," the statement said. "The resignation follows a meeting with Cricket Australia last evening. The resignation is effective immediately."

Langer's manager James Henderson, who also manages Ricky Ponting, Tim Paine and Cameron Green followed up with his own statement on Twitter.

"As a player Justin retired on top after a 5-0 Ashes whitewash," Henderson wrote. "Today, despite the views of a faceless few, he finishes his time as Australian cricket coach winning the T20 World Cup and the Ashes. Lest we forget what JL took over in 2018."

Three-and-a-half hours after the news broke, CA released a statement saying that they had offered Langer the chance to stay.

"Cricket Australia has accepted men's team head coach Justin Langer's resignation, which was received today," the statement said. "Justin was offered a short-term extension to his current contract, which sadly he has opted not to accept.

"The contract extension offered to Justin was the result of a thorough review process that evaluated many factors including future requirements of the team and the upcoming extensive schedule of fixtures.

"The extension was approved by the CA Board and was put to Justin last night. It included the opportunity to defend the T20 World Cup title in Australia at the end of this year."

Senior assistant Andrew McDonald has been named interim coach. McDonald was already set to coach the T20I series against Sri Lanka while Langer rested. He will now lead Australia's tour of Pakistan with another assistant likely called into the fold on a short-term basis.

"Justin has been an outstanding coach of the Australian men's team over the past four years," CA chief executive Nick Hockley said on Saturday. "He has restored the trust in the team and his legacy is assured.

"We are extremely proud of his achievements since he took over in 2018, including the recent T20 World Cup victory and Ashes success. We are naturally disappointed Justin has decided against continuing as coach but respect his decision and wish him all the best in the future.

"I would like to sincerely thank Justin and also his family for all that they have given to Australian cricket over the past four years, for which we remain eternally grateful."

Langer's decision comes less than 24 hours after a marathon eight-hour CA board meeting where his contract was discussed at length. Langer's current deal was due to expire in June and he was seeking a long-term extension. Langer had held multiple contract discussions with CA chief executive Nick Hockley and head of national teams Ben Oliver between the end of the fifth Ashes Test in Hobart and yesterday's board meeting.

CA made a statement on Friday night following the meeting that it had entered into "confidential discussions with Justin and the outcome will be announced as soon as possible."

Langer has walked away from the job he coveted after those discussions. The views of senior players have played a big part in Langer's resignation with his relationship with certain players fractured for nearly 12 months.

The meetings were mediated by Hockley and former CA chairman Earl Eddings. At the time CA said Langer would remain as coach through the T20 World Cup and the Ashes. Langer himself held over 30 individual zoom meetings with players and staff while in quarantine to hear complaints about his coaching style. He vowed to change his style and believes he did through the T20 World Cup and Ashes where he was far less involved in the day-to-day coaching and far more relaxed than he had been previously.

Australia won the T20 World Cup and the Ashes handsomely and Langer believed that would be more than enough to retain his job moving forward.

But Cummins and Finch failed to endorse Langer publicly when repeatedly asked in the media if they would like him to continue as head coach long-term. Both captains were consulted by Hockley and Oliver about Langer's position privately.
