Campaigners to get Britain out of the European Union have moved into the lead, according to a YouGov poll that increases the pressure on Prime Minister David Cameron with less than three weeks until the referendum, Bloomberg reported Monday.

The online poll for ITV's Good Morning Britain program Monday put "Leave" voters at 45 percent and "Remain" at 41 percent, with 11 percent undecided, according to an e-mailed statement. 

The poll comes on the back of others showing Brexit campaigners narrowing the gap or even leapfrogging "Remain" in the debate to sway voters ahead of the June 23 ballot.
