The short-term nature of the election has significantly reduced the amount of time and money that can be spent on campaigning, and is expected to lead to a decrease in party spending of nearly £15m.
Election spend can be broadly broken down into three categories: administrative costs, opportunity costs as the election period detracts from day-to-day life, and campaigning costs spent by political candidates.
In 2015 the Conservatives were the biggest spending party on a national level, with a sum of £15.6m – around £3m more than Labour. However, this was actually smaller than in 2010, when the Conservatives spent £16.8m.
In total, £39m was spent by a total of 57 parties and 23 non-party campaigners in the run-up to the 2015 election.
What happened in the 2015 election?
After 2015’s General Election, David Cameron’s Conservative Party emerged victorious – winning 331 seats, which is enough to form a majority government.
A ruthless strategy of targeting Lib Dem seats meant that the Tories made a net gain of 24 seats – leaving Nick Clegg with just eight.
Labour were the second largest party, although their loss of seats led to the resignation of Ed Miliband. Despite their vote share increasing marginally, the loss of almost all of their Scottish constituencies to the SNP meant that the party had a net loss of 26 seats.
