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. William Hill lengthened its odds for Brexit to 7/2 from 10/3, indicating a 22 percent chance of Britons voting in favor of a withdrawal from the EU. As polls have given sharply different pictures of public opinion, many investors are watching betting odds closely. Odds have consistently indicated a high probability of an 'In' vote in the referendum.
