Voters go to polls in UK local elections It is judgement day for Britain's Conservative prime minister David Cameron, as millions of voters go to the polls in local authority and mayoral elections. According to analysts, the opposition Labour party is set to make gains. The economy is expected to be a major determining factor. It contracted in the UK last year, denting Cameron's credibility. However, in London, polls suggest the charismatic Conservative Boris Johnson is likely to hold on to the job of mayor, for a second term. He is going up against former Labour mayor Ken Livingstone and five other candidates. Five thousand new councillors, who control local planning and spending issues, will be elected in the polls. Turnout is normally low. However, the elections are an important yardstick in gauging public opinion ahead of parliamentary elections, which are due in the UK by 2015.
