The "remain" camp held a 15-point lead over its "leave" rivals in Britain's EU referendum campaign, according to the latest poll from ORB for the Telegraph newspaper, published Monday.

The poll found that among all respondents, support for remaining in the union stood at 55 percent, while that for the so-called "Brexit" option was at 40 percent.

Britons will vote on June 23 on whether their country should remain in or leave the 28-member bloc.

The "remain" camp held an eight-point lead over its "leave" rivals in a separate ICM poll for the Guardian newspaper, also published Monday.
