LONDON (Reuters) - British Prime Minister Theresa May’s Conservative Party has a 15 point lead over the main opposition Labour Party ahead of a June 8 national election, according to an opinion poll conducted by Opinium Research.

The Conservatives were at 47 percent, up 1 percent from Opinium’s previous poll a week ago, against Labour’s 32 percent, up 2 percent.

The poll put the centrist Liberal Democrats on 8 percent, down 1 percent, and the anti-European Union UK Independence Party at 5 percent, down 2 percent.

Opinium Research carried out an online survey of 2,003 UK adults from May 9 to May 12.
