Britain's Prime Minister Theresa May speaks at an election campaign rally near Aberdeen in Scotland
LONDON (Reuters) - British Prime Minister Theresa May's governing Conservative party has a 17 point lead over Labour, an Opinium poll showed on Saturday, slightly down from last week as support for smaller parties slipped.
The Conservatives were on 47 percent, up 2 points from last week, while the main opposition Labour Party gained 4 points to 30 percent - still putting the Conservatives on course for a sweeping victory in June's national election.
Support for the pro-EU Liberal Democrats fell 3 points to 8 percent, and for the eurosceptic UKIP by 2 points to 7 percent.
The poll was conducted on April 25. The number of respondents was not immediately available.
