U.K. Campaign to Stay in EU Has Widest Poll Lead in 3 Months

  • Pound rises against Euro and Dollar after survey is published
  • Prime Minister David Cameron’s Tories split over EU referendum

A U.K. opinion poll showed the biggest lead in three months for remaining in the European Union in next month’s referendum. The pound rose.

The Ipsos Mori telephone survey for London’s Evening Standard newspaper showed 55 percent of respondents saying they’ll opt to stay in the 28-nation bloc in the June 23 referendum, up from 49 percent last month. Support for a so-called Brexit fell to 37 percent from 39 percent, with 8 percent undecided. The 18 percentage-point lead is the biggest since mid-February and it was the second poll in as many days to show a double-digit lead for “Remain.”

The poll will provide a boost to Cameron, whose Conservative Party is split down the middle on the issue. While the premier and Chancellor of the Exchequer George Osborne are campaigning for a “Remain” vote, Justice Secretary Michael Gove and former London Mayor Boris Johnson want to quit. Wednesday’s poll showed that the largest shift in voting intentions was among Conservative supporters, according to the pollster.

“Remain has been boosted by a Conservative swing, but they are also more likely to change their mind, so in this volatile election, with voters divided over the short and long-term impacts of their decision, nothing can be taken for granted,” Ipsos Mori Head of Political Research Gideon Skinner said in an e-mailed statement.

The pound jumped to a new two-week high against the euro and reversed its drop against the dollar after the poll was published. It appreciated 0.7 percent to 77.70 pence per euro as of 12:35 p.m. London time. The U.K. currency rose 0.4 percent to $1.4527, reversing a drop of as much as 0.4 percent.

Ipsos Mori surveyed 1,002 adults by phone between May 14 and 16. It didn’t give a margin for error.

An ORB poll for the Telegraph on Tuesday showed remain leading on 55 percent support, compared with 40 percent for a leave vote.
