A poll has put the Leave campaign six points ahead in the EU referendum campaign.

The opinion poll for the Guardian newspaper by ICM has the Leave campaign on 53% with Remain trailing behind on 47%.

With this result added to the latest polls it puts the Leave campaign ahead of Remain in the average poll of polls with the pro-Brexit campaign out-polling Remain by 52% to 48%.

Polling expert Professor John Curtice, of Strathclyde University, said the latest ICM poll is "consistent" with recent polls.

Professor Curtice said: "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.

"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".

Throughout the referendum campaign online and phone polls have provided markedly different results.

This particular survey is a combination of both polling methods.

ICM interviewed a random sample of 1000 adults by telephone from June 10 to June 13, 2016.

The company then separately interviewed 2001 adults aged over 18 and online, also from June 10 to June 13.

The referendum will take place on June 23. It is the first referendum on Britain's membership since 1975.
