ELECTIONS LIVE: Sadiq Khan to become new London mayor

• The official result in the election for the next Mayor of London is expected to come in at some time after 6 p.m. BST.
• Labour candidate Sadiq Khan will succeed Boris Johnson, after leading the count throughout the day and getting 44% of first preference votes. His Conservative rival Zac Goldsmith received 35% of votes. Any other result is hugely unlikely to happen.
• Four London boroughs have already declared their results, with two going to Labour and two to the Conservatives.
• A Labour victory in London gives leader Jeremy Corbyn a reason to celebrate after what has been a tough day for the party in Scotland. Labour were beaten to second place by the Conservatives in the Scottish Parliament elections.
• It comes after a mixed day of results in other provincial elections. Labour won the most seats in the Welsh Assembly elections, but fell just short of reaching a majority.
• In England, Labour became the first opposition party to fail to increase its seats during a mid-term election since the 1980s, but the party's vote share nationally is expected to be up.
