General elections were held on December 10 of 2015 to elect all 632 members to the House of Commons of the United Kingdom. Voting took place in all 67 counties of the United Kingdom using the Single Transferrable Vote (STV) voting system. The general election was the first general election to be held after the second reform of the voting system, moving away from MMP to STV (MMP had been adopted for the 2012 election).

While the Unity Party (former Unity Movement), Prime Minister Harold Saxon's centrist party, remained at the top of the polls, it lost nearly two-thirds of its electorate and the MPs it returned, falling from a near absolute majority to a paltry 17% of the vote. All other parties benefitted from the massive change that ocurred in this election, considered realigning after the end of Unity dominance after the resignation of Prime Minister Harold Saxon after over 20 years in the premiership. While the Liberal Party came second (extremely closely to its coalition allies the Conservatives) at roughly 14% of the electorate each, the Compassion Coalition was able to achieve a larger gain in seats in sum, and Hilary Benn, leader of the Social Democratic and Labour Representation Committee, was elected Prime Minister.

This election marked the end of the Unity Era, starting at the 1995 general election, which saw unprecedented single-party control over Parliament. The Unity Party received one of the largest swings against of any party in the history of modern democracy. Tim Farron, having been elected leader of Unity just a few days before, did not resign, claiming that the result was entirely expected.

The general elections of the result were the most fractious in British history, with sixteen parties represented in Parliament and none of the two major blocs (the left-wing Compassion Coalition or the Right Bloc on the political right) achieving a majority in the House of Commons. With 249 seats, the Compassion Coalition was slightly closer to the goal than the Right Bloc, and thus began negotiations with the 51 regionalist MPs and Unity. When talks between Unity and the right-wing broke down, the leader of the Liberals (and prospective Prime Minister) Dave Cameron complained about the "democratic injustice in the national elections", claiming that, as the fourth largest party, the Social Democrats had no mandate at all to rule. While this claims would be mostly wavered off by most of the left-wing parties, it remained an important issue of contention.

Unity agreed to sit in crossbench to the Left Bloc, as did the Nationalist parties, leading to a relative majority, which allowed for Confidence on Hilary Benn and his election as Prime Minister of the United Kingdom as part of a minority government. With several Unity backbenchers wishing a return to power or an alliance with the Right despite Farron's "patience and fairness" views (that declared Unity would sit in crossbench to any government, but would favour the largest bloc), the Compassion government is relatively unstable.
