Ed Miliband, leader of the U.K. opposition Labour Party, waves to supporters as he arrives for an election rally ahead of the May 7 general election, while campaigning at the Little Theatre in Leicester, U.K., on Thursday, April 23, 2015. Miliband, who has said he wants to encourage businesses that are "producers'' rather than "predators,'' denies this makes him an enemy of corporate Britain.
