A Most Uncertain Election: In Pictures

The U.K. election on May 7 saw major upsets occur and pollsters proved wrong. David Cameron remains prime minister, with the Conservative Party ruling in its own right and free of the previous coalition government commitments. The biggest impact of a Conservative victory may be that Cameron can now press ahead with his promised referendum on leaving the European Union, to be held by the end of 2017.

    While the Labour and Tory campaigns failed to inspire the electorate -- the polls stubbornly refused to budge since the beginning of the year -- other parties such as the Greens and Plaid Cymru from Wales engaged voters who were sidelined for decades. In the end the pollsters were way off target in their predictions.

    Forecasts of seat numbers suggested that the Tories and Liberal Democrats were unlikely to gain a enough seats to reprise their coalition of the past five years. Ahead of the vote strategists thought they might get close to one with the support of the Democratic Unionists, who won eight of Northern Ireland’s 18 seats in 2010.
