Jennifer Arcuri

... is an American technology entrepreneur, who lived in London from 2011 to 2018. Her friendship with Boris Johnson from 2012, when he was Mayor of London, came to national attention in the UK in September 2019 when he became Prime Minister, triggering investigations into alleged conflicts of interest.

The Sunday Times reported that Johnson was a regular visitor to Arcuri's flat, implying they were in a sexual relationship. Her company, Innotech, was awarded £10,000 from a mayoral fund in 2013, and in 2014 Arcuri was awarded £15,000 from a government programme. Johnson intervened to allow her onto three trade mission trips. The Sunday Times claimed in September 2019 that Johnson had failed to declare his personal relationship as a conflict of interest.

The Greater London Authority then referred Johnson and his actions in the matter to the Independent Office for Police Conduct (IOPC) "so it can assess whether or not it is necessary to investigate the former mayor of London for the criminal offence of misconduct in public office". The IOPC is involved because the Mayor is also London's police and crime commissioner. The London Assembly commenced its own investigation, but paused it at the IOPC's request in order to avoid overlap. On 9 November 2019 The Grauniad reported "fury" after the IOPC shelved its inquiry until after the General Election of 12 December. Westminster politicians and London assembly members, reported the Grauniad, said that a ruling appeared to have been "suppressed" in order to protect Johnson from potentially damaging headlines at a crucial stage of the election campaign.
