London, Oct 25 (PTI) Rishi Sunak will take charge as Britain’s first Indian-origin Prime Minister after an audience with King Charles III on Tuesday, a day after he was elected the new leader of the Conservative Party in a historic leadership run. Outgoing Prime Minister Liz Truss will chair her final Cabinet meeting at 10 Downing Street on Tuesday morning before she makes her way to Buckingham Palace to formally tender her resignation to the 73-year-old monarch. Sunak, 42, will then arrive at the palace for his meeting with the King, who will formally anoint him as the UK’s new Prime Minister.
