Sir Keir Starmer is set to become the UK's first Labour prime minister since 2010 after his party's landslide general election victory, El.kz cites BBC.
Labour is returning to power with a huge parliamentary majority of 174, following a collapse in support for the Conservatives.
Sir Keir will be formally appointed by the King at Buckingham Palace later and then make his first speech in Downing Street.
He is then expected to begin appointing his new cabinet on Friday afternoon, before it meets for the first time on Saturday.
Speaking in central London, Sir Keir told a crowd of Labour supporters that "change begins now", adding: "It feels good, I have to be honest."
Labour's victory has come largely as a result in a dramatic 20 point drop in Tory support, with the party down 249 seats to 119, a historic low.
