The Conservative party is spending more then £100,000 a month on maintaining its Facebook presence, according to documents obtained by the BBC.
In an attempt to build the party's social profile in the run-up to the 2015 election, the Tories were billed £122,814 by Facebook in September 2014, including £25,000 for Facebook 'likes'.
Another invoice from November 2014, obtained by Political Scrapbook, shows a £115,000 bill with £35,000 being spent on likes.
While it's free to join Facebook, it's possible to pay to boost posts, place ads and also to gather paid-for 'likes' to boost a Facebook page's follower count.
Despite the Tories' social media campaign to get David Cameron re-elected, the Conservative Party Facebook page has just 341,480 likes while far-right political party Britain First has almost double at 649,270.
UKIP's Facebook page has 333,047 likes while Labour has 211,724. The Labour party reportedly spends less than £10,000 a month on its Facebook presence.
According to We Are Social, UKIP had the fastest growing Facebook community in the three months up to January 2015.
