Labour leader Keir Starmer has become British prime minister hours after his Labour Party swept to power in a landslide victory. Starmer led his party back to government less than five years after it suffered its worst defeat in almost a century. But Labour also faces a mammoth task of reinvigorating a stagnant economy and dispirited nation. Conservative leader Rishi Sunak in a farewell address said he understood voters' anger and took responsibility for the loss. He then went to Buckingham Palace and offered his resignation to King Charles III.
