For the first time since he became mayor of London on May 2, Boris Johnson has overtaken Conservative leader David Cameron in “favourability”, according to an opinion tracker published on www.politicshome.com.

Johnson scored a rating of 3, up from -7 at the end of April, while Cameron got rated 1, up from -5.

The PHI5000 tracker is based on replies from a politically balanced group of 5000 voters across the UK, who answer a survey every day for the site, which was launched in April and is powered by opinion pollsters YouGov.

The panel are asked daily questions on a rotation system, covering their attitudes to the whole political landscape. As part of this, politicshome tracks a wide range of political personalities, including Cameron’s and Johnson’s favourability ratings.

Because of the consistency of the sample and questionnaire of the tracker, the site is able to track subtle changes in public opinion, it says.

Conservative Leader David Cameron conceded this week he had broken his promise to end “Punch and Judy” politics in the House of Commons.

“I will absolutely hold up my hands and say this is a promise I have not been able to deliver,” he told BBC Radio’s Today Programme on Tuesday.

As if to prove his point, a day later Cameron accused Gordon Brown at Prime Minister’s Questions of political calculation over the 10p tax abolition and the proposed extension of pre-trial terrorism suspect detention to 42 days.

A day before local elections in England and Wales, Cameron said: “With 10p it was about trying to pose as a tax cutter. This time (on 42 days) its about trying to pose as being tough on terror.”

To uproar Cameron added: “He is putting political calculation and self interest ahead of the right decisions on the national interest.”

Brown retorted: “This is the man who wants to be both tough on crime and hug a hoodie at the same time.

“This is the man where political calculation meant he cycled to work but at the same time he had the chauffeur-driven car coming behind.

“This is the man who is a shallow salesman and never addresses the substance of the issue.”

The exchange of personal comments was too much for Liberal Democrat MP Julia Goldsworthy who told BBC television afterwards that the language used was “more suited to the playground.”

“This is the one opportunity a week to hold the prime minister to account, and I think a lot of the rowdiness is a sad reflection on the behaviour in the House of Commons.”
