United Kingdom: In London Mayoral Election, More Than City Hall Is at Stake | Wall Street Journal

Londoners will elect a new mayor on Thursday in a race that pits the son of a billionaire against the son of a bus driver and presents an electoral test for the Conservative Party ahead of a referendum on whether the U.K. should leave the European Union. A loss for the Conservative candidate, Zac Goldsmith, would be a setback for the party of Prime Minister David Cameron. But it could also help Mr. Cameron in his campaign to keep Britain in the EU, less than two months before the June 23 referendum: Mr. Goldsmith, one of the U.K.’s richest politicians, backs a British exit from the bloc and says it would benefit London.
