LONDON — Britain's opposition Labour Party moved a step closer to selecting a leader from its left wing on Saturday, after surprise contender Jeremy Corbyn received the backing of more local party groups than any other candidate. Reeling from its worst election defeat in decades, the party is seeking a successor to Ed Miliband, who stood down as leader. The contest so far has been dominated by the unexpected popularity of Corbyn, who has been a member of parliament since 1983 and at 66 is two decades older than his rivals. Corbyn had received endorsements from 152 local Labour Party groups and the backing of Britain's biggest trade unions by a Friday deadline, figures released by the party showed. That put him well ahead of the next most popular candidate, Andy Burnham, who was endorsed by 111 local parties. — Reuters
