Barnaby Joyce’s remarks further shake the political position of the prime minister, who must call a federal election by May.
Morrison said in a statement on Saturday that he accepted Joyce’s apology. In a leaked message, the deputy prime minister, who heads the junior partner in Morrison’s coalition government, said last year that he had never trusted Morrison.
“He is a hypocrite and a liar from my observations and that is over a long time,” Joyce wrote to a former staffer of Morrison’s Liberal Party who had alleged sexual assault by a fellow staffer.
“I want to apologise to the prime minister … I should have never written the text that I did,” Joyce told a news conference.
“My view from the backbench about the prime minister was based on assumption and commentary, not from a one-on-one working relationship.”
Joyce became deputy prime minister in 2021 as the leader of the National Party, not as Morrison’s appointee. Joyce’s party, which has the power to remove him as its leader, did not immediately reply to requests for comment.
Joyce’s text message, first reported on Friday night by Nine Newspapers, was sent through a third party to former Liberal Party staffer Brittany Higgins. She had alleged that she was sexually assaulted in Parliament House in March 2019.
The political commotion comes just days after a controversy about an alleged exchange between senior Liberal Party members making derogatory remarks about Morrison.
Opposition Labor leader Anthony Albanese said it was “untenable” for Joyce to continue as deputy prime minister.
