The past few days have been a period of crisis for both pro-Europe Tory and Labour leaders in the United Kingdom in the run-up to the June 23 referendum on Britain’s exit from the European Union: The British electorate looks increasingly willing to cast off EU membership. Just this past week, six consecutive polls have showed the “Leave” campaign ahead of “Remain” by as little as three points and by as much as seven.

If there’s hope for the British establishment, it may be found in, of all places, the betting markets. While betting markets have tightened substantially in recent days, they’re still implying a roughly 60 percent chance that Britain votes to remain. But why should observers trust bookmakers more than pollsters?
