Nearly 90% of Facebook ads paid for by the Conservative Party in the first few days of December contained misleading claims, an investigation has found. First Draft – a non-profit organisation which works on debunking fake news – analysed every ad promoted by the UK’s three main political parties on the social media giant in the first four days of December. It found 88% of the Conservative’s Facebook campaigning pushed figures challenged by Full Fact, the UK’s leading fact-checking organisation. By comparison, First Draft said that it could not find any misleading claims in ads run by Labour on Facebook over the same period.
