Text messages between Andrew McCabe, the deputy director of the FBI at the time, and Jeremy Fleming, his then counterpart at MI5, now the head of GCHQ, also reveal their mutual surprise at the result of the EU referendum, which some US officials regarded as a “wake-up call”, according to a person familiar with the matter.
In one exchange in August 2016, Fleming noted that members of the FBI and MI5 had “met on our strange situation”, a veiled reference to discussions about Russian activities, according to the source
When Boris Johnson, the UK foreign secretary at the time, was asked in November 2017 whether Russia had played any role in British elections, he told MPs in a select committee that he had not seen any evidence of such an occurrence.
When asked in a follow-up if Russia had sought to play a role, Johnson said: “I don’t know about sought to play, but as far as I know they played no role.”
The new revelation comes as authorities in the UK are investigating the funding behind a pro-Brexit campaign, and whether it might have included illegal foreign donations. The National Crime Agency (NCA) is investigating the insurance executive and political donor Arron Banks, who was suspected by the UK’s Electoral Commission of not being the “true source” of £8m in funding to the Leave.EU campaign. The matter was referred to the NCA by the commission after it said it had “reasonable grounds” to suspect a number of criminal offences.
