The U.K. voted 52% to 48% to leave the European Union in a referendum that revealed deep divisions within political parties, across generations and between geographic regions of the Commonwealth.
Markets felt the first real impact of the results. The pound plunged as much as 11% to $1.37, the weakest level since 1985, before recovering a bit. The Stoxx Europe 600 Index sank 6.6% as of 9:50 a.m. in London, heading for its biggest decline since 2008.
