My interview on BBC Radio Foyle about Facebook’s fact-checking operation which is launching in the UK, with the independent charity Full Fact selected to be the first British publisher to review and rate the accuracy of content on the social network. Posts, links and videos that have been flagged as false will be marked as such to users, and people will be warned if a post they are about to share has been found to be false, but no one will be stopped from sharing or reading any content, false or not.
