Boris Johnson told Jennifer Arcuri he was her ‘number 1 supporter’ after saying he ‘blown her off’

Boris Johnson reportedly texted Mistress Jennifer Arcuri’s B ****** s, I’m your No1 supporter after she was accused of ‘calling her off’.

The American entrepreneur is said to have reprimanded the then mayor of London for not attending an event in the capital in which she was involved.

It comes after the 36-year-old admitted to having a four-year affair with Mr. Johnson – starting in 2012.

According to the Sunday MirrorMs. Arcuri was angry because she had received support from then-Prime Minister David Cameron and Chancellor George Osborne, but apparently not from Mr Johnson.

In an October 2015 text seen by the newspaper, she told Mr. Johnson, “ Osborne is giving me a building. PM confirms my event … And you?

‘And you? You’re ignoring me … (again). And blow me off for the 8th. ‘

But Johnson replied, “Bollocks. I am your main supporter and have been for years. ‘

MailOnline has contacted a No10 spokesperson for comment.

The latest revelations come after extraordinary emails revealed how Mr. Johnson’s lover clashed with his officials about his appearances at her corporate events.

Official reports reveal how Ms. Arcuri signed up Mr. Johnson to speak at top technical conferences without his City Hall staff knowing.

The American entrepreneur had to be told by exasperated officials, “Couldn’t you please go straight through the mayor?”

In one message, Miss Arcuri appeared to address Mr. Johnson as’ sweetheart ‘and asked,’ May I apply for this October missionary trip? Come with me when we go 😉 ?? !!!! ‘

The 240 pages of emails and documents are likely to be examined by the Greater London Assembly’s oversight committee as it investigates whether or not the then mayor gave preferential treatment to Miss Arcuri and her firms InnoTech, Playbox and Hacker House.

It comes after the 36-year-old admitted she had a four-year affair with Mr. Johnson, including claims of sex on the couch of his family home while his wife was at work.

The emails date back to early 2013, the year after she claimed the couple started seeing each other, when Miss Arcuri wanted Mr Johnson to hold his first ‘Google Hangout’ video meeting at her InnoTech Summit in Canary Wharf. She promoted him as the main attraction of the event before his staff heard about it.

In a message to an unnamed official, she wrote: “I don’t want to do anything to deter anyone at the mayor’s office, but I do need to get promoted. As you know we have all of Los Angeles and San Fran coordinating and so for this event we also have to work with them logistically.

“If you have any questions about the validity of this event, please contact Boris himself, as he was my point of contact.”

A senior official replied: “In our conversation, the mayor is incredibly busy and we would appreciate it if the mayor came through the cabinet. The mayor sometimes cannot see his diary and I have had to rearrange the diary considerably to accommodate this event.

“Please can’t you go directly through the mayor. Also as discussed, feel free to list the mayor as a speaker on the website, but you can remove him as a partner or sponsor. ‘

Ms. Arcuri later drafted a press release that included a quote from the mayor, but it was modified by City Hall to make it “much less strange.”

In the fall of that year, Ms. Arcuri told people that Mr. Johnson would be attending an event of hers at the World Islamic Economic Forum at the ExCel Center in London.

She told an employee that his appearance had been ‘confirmed’, but they replied, ‘Unfortunately, the mayor cannot be present.’

An intriguing freedom of information disclosure email, dated July 2015, was sent by Ms. Arcuri to a person in City Hall whose name had been removed, and appeared to refer to a trade mission to Israel that she and Mr. Johnson were both attending .

It said, “Dearest [redacted]Can I sign up for this October mission trip? I really must visit this Hacker house !!! Come with me when we go 😉 ?? !!!!! Xxx ‘

Downing Street declined to comment, but on Monday, Johnson’s press secretary Allegra Stratton insisted, “He believes in the broader principles of integrity and honesty.”

She pointed out that he had been cleared of all impropriety by the Independent Office for Police Conduct last year.

The London Assembly’s oversight committee has already investigated whether Mr. Johnson violated the mayor’s code of conduct by not disclosing the relationship, or misused his position in favor of his mistress.

In 2019, it was revealed that Ms. Arcuri had been given £ 126,000 in public money and privileged access to three official overseas trade missions led by him, leading to allegations that he had abused his position to benefit her.

Last month, a city hall source said the commission would now investigate Miss Arcuri’s new evidence.

The source told MailOnline that the new revelations in Ms. Arcuri’s interview with the mirror were significant in that it suggested that there had been a ‘substantial relationship’ over a long period of time.

The source also noted that Ms. Arcuri had said she felt Mr. Johnson should have explained their relationship and said officials would be interested in this.

Last year, the Independent Office for Police Conduct (IOPC) decided not to open a criminal investigation into the allegations, although officials said he should have reported the relationship.

The committee investigation will take place after the elections on 6 May.

A spokesperson for No. 10 previously told MailOnline that it had “nothing to add” to the claims.
