Two of the most senior intelligence officials in the US and UK privately shared concerns about “our strange situation” as the FBI launched its 2016 investigation into whether Donald Trump’s campaign was colluding with Russia, the Guardian has learned.

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.

While Russia had previously been viewed as a country that would seek to interfere in western elections, the Brexit vote was viewed by some within the FBI as a sign that Russian activities had possibly been successful, the person said.

Their exchanges offer new insights into the start of the FBI’s Russia investigation, and how British intelligence appears to have played a key role in the early stages.

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.
