When Theresa May called for snap elections on April 18, the Tories had a 20 percentage points lead over the Labour in opinion polls, a lead unobserved since 2008/2009. Actually, the Labour and UKIP fell in opinion polls after the Brexit referendum. Even if polls still indicate a clear victory of Tories, the lead of the Tories has tightened sharply in the recent weeks. It is interesting to underline that the pound has depreciated versus the euro when this lead has tightened as a large Tories’ victory would be interpreted as favoring a smoother Brexit process.
