On May 7, the British electorate will go to the polls in the 2015 general election. Voters will elect their local members of parliament. It seems voters may not, however, be able to choose their next government.
As in 2010, current polling data suggests a hung parliament, in which no political party can achieve an outright majority. Governance requires the confidence of the House of Commons. Of the 650 parliamentary seats, then, a ruling coalition requires the backing of at least 326 MPs.
For the past five years, Prime Minister David Cameron's Conservative Party has retained the confidence of the House through a reasonably successful and stable coalition with the Liberal Democrats.
