Western Australian Premier Mark McGowan has called billionaire Clive Palmer the nation's 'greatest egomaniac', telling him to drop his case against his state government over its border closures after the Commonwealth withdrew its support.
Prime Minister Scott Morrison has written to Mr McGowan saying the Commonwealth will no longer participate in the case, after taking into account the changed state of the coronavirus pandemic that has worsened since the matter was first brought to court.
Mr McGowan thanked the prime minister for his letter and for listening to his government and the people of WA.
'I'm very grateful the Commonwealth has pulled out,' Mr McGowan told reporters in Perth on Sunday.

He said Brisbane-based Mr Palmer, who leads the United Australia Party, should also withdraw and is prepared to fight him in the High Court if he doesn't.
'He is showing himself at this point in time to be Australia's greatest egomaniac,' the premier said
'Mr Palmer can now solve this matter by withdrawing his action. He is not acting in the interests of the people of Western Australia, he is only acting for his own interest.'
