The election saw each of Parliament's 650 constituencies return one MP to the House of Commons. It resulted in a Conservative majority, a massive loss of seats for the Liberal Democrats, and all but three Scottish seats going to the SNP.
UKIP won its first seat at a general election. Alliance and Respect each had their representation from the last Parliament wiped out. The UUP won representation after none in the previous Parliament.
Below is a graphical representation of the House of Commons showing a comparison of party strengths as it was directly after the 2015 general election. This is not a seating plan of the House of Commons, which has five rows of benches on each side, with the government party to the right of the Speaker and opposition parties to the left, but with room for only around two-thirds of MPs to sit at any one time.
See here for a full list of changes during the fifty-sixth Parliament.
In addition to the parties listed in the table above, the Co-operative Party was also represented in the House of Commons by Labour MPs sitting with the Labour Co-operative designation. The number of these MPs was 24 after the general election, and was 28 at dissolution.
The actual government majority is calculated as Conservative MPs less all other parties. This calculation excludes the Speaker, Deputy Speakers (two Labour and one Conservative) and Sinn Féin (who follow a policy of abstentionism).
