Sir Keir Starmer has become the UK's new prime minister after Labour's historic landslide victory, ending 14 years of Conservative rule. The election saw Labour win 410 seats in the 650-seat House of Commons, with outgoing Prime Minister Rishi Sunak offering his resignation to King Charles III. Starmer's victory is seen as a 'loveless landslide' with a vote share lower than previous Labour triumphs under Tony Blair and Jeremy Corbyn. The new government faces significant challenges, including reviving the economy and restoring public trust. This transition marks the third prime ministerial change since King Charles III's reign began. Starmer has pledged to bring 'the sunlight of hope' to a dispirited nation.
