Reform UK mayor Luke Campbell is being investigated by police after allegedly showing four naked and sexualised images of himself to a female member of staff at his office in Hull.
Mr Campbell, 39, is said to have called the senior employee to his desk at the Hull and East Yorkshire Combined Authority (HEYCA) in May. The incident was allegedly witnessed by another colleague.
He was interviewed under caution by Humberside Police earlier this month, but has not been arrested or charged with any offence.
The woman is understood to have felt “shocked, embarrassed and humiliated” after being shown the images. Documents relating to her complaint allege that Mr Campbell and other male members of staff laughed at her reaction.
She said: “I was deliberately exposed to naked and sexualised images involving the mayor in the workplace, without my consent, and was laughed at when I was visibly embarrassed.” She added that the experience “violated my dignity”.
A separate account was provided by a colleague who is said to have witnessed what happened. Other allegations involving Mr Campbell include an incident in which he allegedly lowered the waistband of his trousers to reveal a tan line and a tattoo on his lower abdomen.
The woman was reportedly offered a permanent job, but that offer was withdrawn three weeks after the alleged incident. The matter is now subject to internal proceedings by HEYCA after she claimed the offer was withdrawn because she rejected unwanted sexual contact.
A HEYCA spokesman said the combined authority had processes for complaints about elected members and officers, adding: “The standards process and the complaints procedure must be carried out in a fair and independent manner.”
A Reform UK spokesman said: “Luke firmly denies the allegations. They come from a disgruntled employee attempting to leverage a settlement in a meritless workplace dispute.”
Mr Campbell became mayor of Hull and East Yorkshire in 2025, having not previously been involved in politics. He won a boxing gold medal at the 2012 London Olympics and has been awarded an MBE.
His office has previously faced allegations of a “toxic working environment”, including claims that he demanded five members of staff resign after accusing civil servants of undermining him.
There was also a dispute over whether he could claim first-class train travel on expenses, a claim denied by Reform UK. An independent remuneration panel later recommended that he could claim only for standard-class travel.
