Boris Johnson Leads Ken Livingstone By Six Points Following Tax Row

Ken Livingstone is trailing Boris Johnson by six points in the race to become the next Mayor of London, according to a poll published on Tuesday.

A ComRes survey carried out for the Evening Standard, LBC and ITV showed that the incumbent Conservative mayor is favoured by 53% of Londoners compared to 47% who back his Labour rival.

The poll was published as Johnson launched his re-election campaign in Richmond, south London, where he branded Livingstone a "champagne-swilling Trotskyist bendy-bus aficionado".

The rivalry between the two men has become increasingly bitter in recent days. In one incident Johnson confronted Livingstone in a cramped lift and called him a "f*****g liar'. The Mayor was upset over allegations made by Livingstone that he avoided paying his fair share of tax.

ComRes surveyed people between 2-5 April, with the argument over the candidates' tax affairs erupting on the morning of 3 April.

Before the argument that began on-air during an LBC mayoral hustings the public were split 50-50 on who they wanted to see elected mayor.

But those asked after the row (10am on Tuesday) favoured Johnson 60% to 40%.

Johnson and Livingstone are trailed by Lib Dem Brian Paddick on 6% and the Green's Jenny Jones on 4%.
