Three polls Saturday showed a rise in support for the opposition Labour Party, although the governing Conservative Party maintained a commanding lead.
The polls showed the party of British Prime Minister Theresa May remained between 11 and 17 points ahead of Labour, still enough to deliver a clear victory as she seeks a mandate ahead of negotiations over Brexit, set to begin in the summer.
However, the polls showed the gap had closed from leads of up to 25 points reported last weekend.
One poll by YouGov showed the Conservative lead over the Labour had fallen to 13 points, compared to the 23 points that the same polling firm found last week.
The YouGov poll for the Sunday Times found that 44 percent were set to back the Conservatives, down from 48 percent last weekend. Support for Labour climbed to 31 percent from 25 percent.
May said April 11 that she would look to hold an election June 8, to secure a mandate for her plan for leaving the European Union.
A further tightening in poll ratings might generate more uncertainty over what Britain’s position will be when it sits down in June to begin negotiations in earnest.
Is Conservative support falling?
However, despite the narrowing gap, pollsters were divided over whether support for the Conservatives was actually falling.
An earlier poll by Opinium showed support for the Conservatives had risen 2 percentage points, but the gap between the biggest parties narrowed nevertheless as Labour boosted their support by 4 percentage points. Smaller parties saw their share of the vote drop.
The smallest gap between the parties was 11 points in a poll by ORB for the Sunday Telegraph. It showed support for the Conservatives at 42 percent, while support for Labour was 31 percent. It was ORB’s first poll on the election since May called the poll last week, and is not necessarily comparable with polls by other firms.
