EU referendum: leave takes six-point lead in Guardian/ICM polls

Phone and online polls show support for Brexit growing to 53%, with proportion backing remain campaign falling to 47%. From UK’s The Guardian

Support for leaving the EU is strengthening, with phone and online surveys reporting a six-point lead, according to a pair of Guardian/ICM polls.

Leave now enjoys a 53%-47% advantage once “don’t knows” are excluded, according to research conducted over the weekend, compared with a 52%-48% split reported by ICM a fortnight ago.

The figures will make grim reading for David Cameron, George Osborne and the Labour party. They follow a fortnight in which immigration became the dominant issue in the referendum campaign, with the publication of official figures showing that net migration had risen to a near-record 333,000 in 2015.

Prof John Curtice of Strathclyde University, who analyses available referendum polling data on his website whattheukthinks.org, noted that after the ICM data, the running average “poll of polls” would stand at 52% for leave and 48% for remain, the first time leave has been in such a strong position.

“These results are consistent with the generality of numbers over the last couple of weeks, in which there has been some weakening in the remain position,” he said. “It was already plain that this race was far closer than the prime minister intended and he must now be feeling discomfort at the thought that the outcome really could be in doubt.”
