LONDON (AA) – Support for Britain’s EU membership is at its highest level since the start of Brexit referendum campaign, a new opinion poll has found.
The Remain camp has a 55 percent lead over Leave, which was trailing on 42%, according to the ORB survey for the Daily Telegraph.
The poll found older voters, men and traditional supporters of the U.K.’s governing Conservative Party were increasingly persuaded by the arguments of the Remain campaign.
All three were demographics previously identified as strong supporters of a British exit from the European Union.
The poll will be a boost to U.K. Prime Minister David Cameron, who supports British EU membership but is leading a party and a government that is divided on the issue.
Four of his cabinet ministers and former London mayor Boris Johnson are among the prominent figures campaigning for Britain to leave.
Cameron has used campaign appearances in recent days to warn over the economic consequences of Brexit.
His finance minister George Osborne warned on Monday that a decision to leave would plunge the country into a year-long recession and cause the loss of at least half a million jobs.
On Tuesday, Cameron suggested family holidays to Europe would be £230 ($333) more expensive because of a cheaper pound sterling.
Although Leave supporters have accused him of using scare tactics, they have used a similar approach to emphasize their own argument.
Over the weekend, Minister of State for the Armed Forces Penny Mordaunt claimed Britain’s continued membership meant it would be forced to accept a potential 77 million migrants if Turkey joins the EU.
