Sadiq Khan, the Labour Party's mayor of London, romped to victory Saturday, securing a record third straight term at City Hall, on another hugely disappointing day for the U.K.'s governing Conservatives ahead of a looming general election.
Khan won a little over a million votes, or nearly 44% of the vote, more than 11 percentage points ahead of his main challenger, the Conservative Party's Susan Hall. He did particularly well in inner London but struggled in several outer boroughs.
