A Reddit security team believes the user who posted documents relating to US–UK secret trade talks, which were were later used by Labour during the general election campaign, was part of a coordinated campaign originating from Russia.

Jeremy Corbyn hosted a press conference last week, during which he used the same documents as a centrepiece, arguing they showed privatisation of the NHS was being discussed as part of a US–UK free trade agreement.

There's been no doubt about the veracity of the documents. In fact, the Daily Telegraph appeared to report on the substance of some of the documents back in July.

It also remains unclear how Corbyn came in contact with them. However, Labour MEP Judith Kirton-Darling tweeted a link to the Reddit post several days before the press conference.
