Bookmaker William Hill has cut its odds of Britons voting to remain in the European Union in a June 23 referendum to 1/6, the shortest odds to date and indicating a probability of 85 percent. 'During the week just gone, the odds for 'remain' have halved from 1/3 to 1/6 as many political punters seem to have decided they know what the result will be,' William Hill spokesman Graham Sharpe said on Saturday.
