Keir Starmer is set to become the third prime minister during King Charles III's reign, following the recent resignations of Liz Truss and Rishi Sunak. As head of state, one of King Charles's key constitutional duties is appointing new prime ministers, alongside other responsibilities such as the State Opening of Parliament and signing parliamentary bills into law.
Following Sunak's resignation, he will visit Buckingham Palace for a final audience with the monarch, a tradition that involves bidding farewell and expressing gratitude to the reigning sovereign. Former Prime Minister Gordon Brown shared insights from his own experience, noting that his last meeting with Queen Elizabeth II was cordial and relaxed, with a parting gift of an inscribed photograph.
