LONDON (Reuters) - Britain’s governing Conservative party has seen its lead narrow considerably over the last week, a poll by YouGov showed on Sunday, the third poll of the weekend to show the party’s advantage over the opposition shrink.

Prime Minister Theresa May’s Conservative party was set to garner 44 percent of the vote, the poll for the Sunday Times showed, still a commanding 13 point lead over Labour, who polled at 31 percent.

However, a poll by YouGov last weekend had showed a 23 point lead for May’s Conservatives, and two other polls released on Saturday also showed Labour closing the gap on the governing party.

Support for the pro-EU Liberal Democrats was 11 percent, while eurosceptic UKIP polled at 6 percent.

YouGov questioned 1,612 adults between April 27 and 28.
