What a come-back. Just four months after resigning as Chancellor and seven weeks after losing the leadership election to Liz Truss, Rishi Sunak made his first address this afternoon as Britain’s 57th Prime Minister and vowed to “work day in day out to deliver for the British people.”

Speaking at the Conservative HQ in London, the 42 year-old also had a stark warning for his own party: “unite or die.”

Sunak was declared leader early this afternoon, after the only rival left standing, Penny Mordaunt, withdrew from the contest – following Boris Johnson’s exit last night – bringing the snappy five day race to replace Liz Truss to an end.
