LONDON (Reuters) - Prime Minister Boris Johnson’s Conservative Party’s lead over Labour has widened to nine points from six a week ago, according to a poll by BMG for the Independent newspaper published four days before Britain’s election.

The Conservatives are on 41% support, up two points, compared with the previous BMG poll published on Nov. 30.

Labour fell one point to 32%. The Liberal Democrats edged up one point to 14% and the Brexit Party was unchanged at 4%.

Other polls published over the weekend showed the Conservatives ahead of Labour by between eight and 15 points.

BMG polled 1,542 voters online between Dec. 4 and Dec. 6.
