Shortest odds on 'In' since EU vote date was announced - bookmaker

British bookmaker William Hill said on Monday it was offering an "In" vote at the shortest odds since the date of next month's referendum on European Union membership was announced in February. A spokesman for William Hill said 79.2 percent of all the stake money taken was for "In" but 64.4 percent of individual bets struck have been for "Out". As opinion polls have given sharply different pictures of the public mood, many investors are watching betting odds closely.
