Britain's FTSE 100 seen lower after PM May's Brexit deal crush

Britain's top share index was expected to open slightly lower on Wednesday after lawmakers defeated Prime Minister Theresa May's deal to leave the European Union by a crushing margin overnight, deepening political and market uncertainty. The FTSE 100 was seen opening 3 points lower and underperforming its European peers, according to financial spreadbetters at IG. The small drop comes as sterling eked out small gains against the U.S. dollar in early dealings, with the sizable defeat for May seen forcing Britain to pursue different options, including a delay to the exit.
