The New York Times notes foreign disinformation campaigns aren't the only source of misinformation affecting the UK's election, with a significant amount of disinformation tactics originating from UK political parties themselves, along with individual citizens. Both the Labour and Conservative parties have been implicated in this behavior, although the Conservative party has drawn more criticism for some intentionally deceptive tactics, such has disguising one of its Twitter accounts as a non-partisan fact-checking organization.
The Labour party's Jeremy Corbyn cited documents that appeared to show that the Conservatives were using the UK's National Health Service as a bargaining chip in trade talks with the US. These documents, which may or may not be legitimate, were later linked to Russia's Secondary Infektion disinformation campaign. The truth behind the documents, according to Computing, appears to be the fact that the NHS was providing US-based Amazon with free healthcare data, apparently to help Alexa offer better medical advice and therefore taking some of the burden off of the NHS hotline.
An apparently untrue social media post claiming to disprove a photo of a sick child lying on the floor of Leeds Hospital went viral, and it's not clear who was behind the post, Verdict reports. The poster claims to be a good friend of "a senior nursing sister" at the hospital, and says the boy's mother took him off of his stretcher and put him on the floor in order to take the photo. The post was shared by a number of prominent figures, including a Telegraph columnist, in spite of the fact that the hospital had already apologized to the boy's family. The Guardian reported that story was first posted by an account belonging to a medical secretary, and the medical secretary says her account had been hacked. Verdict notes that there's no evidence on the surface that any inauthentic behavior was was used to spread the story, but the viral story "successfully shifted the narrative away from bad publicity for the Conservative Party."
