Australia's Prime Minister Anthony Albanese has warned against a leadership change in the United Kingdom amid reports his British Labour counterpart Keir Starmer could be about to resign.Britain's Observer newspaper is reporting Starmer is expected to resign on Monday and set out a timetable for his departure.The Observer report, which did not name its sources, said Starmer had reached the conclusion that his position was no longer tenable after speaking to cabinet ministers, advisers, donors and trade union leaders.However, a government source said Starmer remained focused on getting on with the job of governing.Asked about the potential change by Sky News on Sunday morning, Albanese said he will "deal with whoever is elected"."But I must say that the history of just changing leaders is not a positive one," he said Scott Morrison and Peter Dutton have also led the party during Albanese's tenure as prime minister.Long-time Nationals leader David Littleproud also resigned in March and was later replaced by Matt Canavan
