Figures released Thursday show Prime Minister David Cameron's Conservatives spent 16.7 million pounds ($25.9 million) on the election that ushered their coalition government to power.

Labour spent just 8 million pounds ($12.5 million) - a drop from the 10 million pounds ($15.6 million) it spent on its 2005 election campaign, which ended with Labour leader Tony Blair's re-election as prime minister.

Total campaign spending on the 2010 vote clocked in at 31 million pounds ($48 million). The Liberal Democrats, now part of the coalition government, spent 4.8 million pounds ($7.5 million).
