Boris Johnson is cruising to victory in the London mayoral election, according to a poll published on Tuesday.
A survey carried out by Populus for The Times shows Johnson is leading his Labour rival Ken Livingstone by 12 points.
According to the poll, Johnson is set to secure 46% of the vote on Thursday compared to 34% for Livingstone in the first round of voting.
After the other candidates are eliminated Johnson would then get 56% of the vote compared to just 44% for Livingstone.
The survey also placed Green Jenny Jones in third place on 6% of the vote, ahead of the Lib Dem's Brian Paddick in joint fourth place with independent candidate Siobhan Benita on 5%.
The margin of victory is the largest given to Johnson at any point during the election campaign.
A YouGov survey for the Evening Standard yesterday gave Johnson a four-point lead of 52%-48%, after second preferences were taken into account.
