In November 2018, Steve Bannon, previously a top aide to Donald Trump, was in the UK preparing for a speech at the Oxford Union.
The event was disrupted by numerous demonstrators, and Bannon, who was due to board a flight that evening, told Jeffrey Epstein in an email: "Protesters slowed down my talk I doubt I can catch the plane we are heading to heathrow".
Epstein replied: "That. Is a gulf air that leaves at 9:50 with a layover in Bahrain". Bannon answered: "U r an excellent assistant".
These exchanges were published on Wednesday together with more than 20,000 documents from the estate of Epstein, the deceased convicted sex offender.
The release by the Congressional committee contains an iMessage chat where Bannon's name is withheld. The BBC has been able to establish his identity by matching the dates, events, and locations referenced.
For instance, Epstein talks about arranging a jet from Scotland for the unnamed individual in the chat, and offers praise their "Oxford speech". Bannon took part in the Edinburgh conference on November 14, and gave the speech at the Oxford Union two days later.
Bannon, who faces no allegations of any wrongdoing, did not reply on the request for comment.
Bannon was one of Trump's closest advisers in the run up to the presidential election and during the initial phase of his presidency, but stepped down from the White House in 2017.
He has admitted he was making a film about Epstein prior to his death and reportedly has approximately 15 hours of footage. In a recording of his show recently, he said: "We plan to publish the series, the five-part series, next year - at the start of next year."
But the recently disclosed documents suggest Bannon's connection with Epstein extended than being his biographer, with the disgraced financier occasionally seeming to act like a personal assistant.
A few days prior to the conversation in which Epstein appeared to have arranged a private plane for Bannon, Epstein said: "how does it feel to have the highest-paid booking agent in history ".
Bannon thanked him: "You are quite capable asst", to which Epstein replied "Massages. Excluded".
Discussing a trip to "AD" in another message, Epstein told Bannon: "I'll make sure you are well looked after."
The published messages also show Bannon and Epstein talking about UK politics in that year.
Earlier on the day of his address at the Oxford Union, Bannon messaged Epstein: "I've gotten pulled into the Brexit thing this morning with Nigel, Johnson and Mogg."
Then, in what seems like a reference to Theresa May, the embattled British leader at the time, he added: "They are trying to proceed. May soon…"
Epstein suggested Bannon: "I think staying as long as you can uk. Best-- so others get the dedication of your follow through."
Shortly after, Epstein asked: "Can Theresa May remain in power". Bannon answered: "I don't see how BUT the guys here have no balls" and added "Johnson ; Gove; Jacob Rees-Mogg; Davis - someone has to take charge".
Theresa May was eventually removed in May 2019 after surviving multiple attempts of lack of support in late 2018.
A representative for Reform UK informed the BBC: "Nigel Farage has not been in a gathering with Bannon, Jacob Rees Mogg and Boris Johnson." And there is no evidence such a meeting took place.
The US House of Representatives will decide soon on whether the Department of Justice should release all its records related to its investigation into Epstein, who died in jail in that year.
Interest in Epstein's associations with powerful figures was renewed recently after the release of over 20,000 pages from his estate.
A portion of those referenced the former president, who has consistently rejected any impropriety. The president was a friend of Epstein's for a long time, but claims they fell out in the 2000s, a couple of years before Epstein was first arrested.
