**Recent allegations against Reform UK mayor Luke Campbell have prompted a police investigation but have not led to an arrest.** The Hull and East Yorkshire mayor, a former Olympic boxer, faces claims he showed a female colleague naked and sexualised images of himself in May 2026, with the accuser alleging the incident contributed to her departure from the role. Campbell was interviewed under caution by Humberside Police earlier in October, yet no charges or arrests have occurred as of mid-to-late October. Campbell and Reform UK have firmly denied the claims, describing them as originating from a disgruntled employee in a workplace dispute. The combined authority has confirmed both the police probe and its own internal standards process, which must proceed independently. Given the early investigative stage, the absence of immediate enforcement action, and the contested nature of the allegations, traders assign a high implied probability to no arrest occurring by year-end.
