Nigel Farage, leader of the U.K. Independence Party (UKIP), left, and Douglas Carswell, a Conservative Party member of parliament for Clacton, react during a news conference to announce the lawmaker's defection to UKIP, in London, U.K., on Thursday, Aug. 28, 2014. Carswell, who represents Clacton in Essex, told a news conference in London today that his decision was sparked by the fact that "many at the top of the Conservative Party simply aren't on our side."
