Britain’s opposition Labour Party has squeezed the governing Conservatives’ opinion poll lead to 11 points from 18 over the last week, a survey by Kantar showed on Tuesday, ahead of a Dec. 12 election.

Support for Prime Minister Boris Johnson’s Conservatives fell 2 points to 43%, while Labour was up 5 points on 32%. The pro-European Union Liberal Democrats were down 2 points on 14%, while the Brexit Party was up 1 point on 3%.

Kantar surveyed 1,097 people online between Nov. 21 and 25.

The poll is the second in two days to show a narrowing of the Conservatives’ lead. On Monday, an ICM poll for Reuters gave the Conservatives a 7-point lead, down from 10 points a week earlier.
