A campaigner for Will Martindale, the ex-JPMorgan Chase & Co. banker and prospective parliamentary candidate for Battersea, Balham & Wandsworth for the U.K. opposition Labour Party, waits at a door with a campaign leaflet in hand, ahead of the May 7 general election, in the Battersea district of London, U.K., on Thursday, April 2, 2015. Martindale is one of a group of candidates with backgrounds in finance, seeking on May 7 to join one of the few professions British voters distrust even more.
