Counter-terrorism police have reopened an investigation into an April 2025 incident in which a lit incendiary device was pushed through the letterbox of Nigel Farage's home, connecting the previously closed case to their ongoing probe into the murder of Ann Widdecombe.

Vicki Evans, senior national coordinator for counter-terrorism policing, confirmed that officers reopened the investigation into the Farage incident as part of the counter-terrorism policing south-east (CTP South East) investigation into Widdecombe's death. The move was prompted by the discovery of a line of inquiry that CTP London now says "may have been relevant" but was "not identified and pursued by [counter-terrorism police] at the time" of the original investigation.

During the initial investigation, police identified no suspects and closed the case pending any new leads. The case stayed dormant until the Widdecombe murder investigation surfaced the overlooked inquiry.

CTP London made a "mandatory conduct referral" to the Independent Office for Police Conduct (IOPC) on 7 August 2026. A mandatory conduct referral is a formal step police forces must take when they identify a potential failing that meets specific threshold criteria in police regulations. The IOPC confirmed it will independently investigate the conduct of a CTP London staff member, following the referral, relating to an allegation that the individual failed to identify and pursue a line of inquiry connected to the attempted burglary reported in April 2025.

Widdecombe, 78, was a Reform UK spokesperson and former Conservative minister. She was found dead on 9 July at her home in Haytor on Dartmoor, Devon, having sustained serious injuries. She had served as Conservative MP for Maidstone, Kent, for 23 years, later represented south-west England as a member of the European Parliament for the Brexit Party, and joined Reform UK in 2023.

A 28-year-old man, Joshua Kerry from Rotherham in South Yorkshire, was charged with Widdecombe's murder. Kerry was arrested on suspicion of murder on 11 July and was rearrested on suspicion of the commission, preparation, or instigation of acts of terrorism. He has not been charged with terrorism offences. The Guardian

Devon and Cornwall Police initially arrested a 26-year-old man from Newton Abbot in Devon but later released him and said he was no longer part of the investigation.

The convergence of these two cases raises the question of whether a single investigative thread links the firebombing at Farage's residence and the killing of Widdecombe, both prominent figures associated with Reform UK and its predecessor movements. Counter-terrorism policing has not publicly elaborated on the nature of the overlooked line of inquiry, but the decision to fold the 2025 case into a murder investigation overseen by CTP South East signals that investigators see a credible connection worth pursuing under counter-terrorism protocols rather than ordinary criminal procedure.

The IOPC's independent investigation into the CTP London staff member introduces a parallel accountability track. The fact that CTP London self-referred suggests internal recognition that the original handling of the Farage case may have fallen short of expected investigative standards. The IOPC will assess whether the staff member's alleged failure to pursue the line of inquiry constituted a disciplinary matter, a performance issue, or something more serious.

The broader context here is the security posture around Reform UK figures. Widdecombe's death on 9 July, the firebombing of Farage's home fifteen months earlier, and the Home Secretary's prompt offer of a security meeting to Farage collectively point to an environment in which the threat assessment for prominent politicians outside the traditional party structure has become a live operational concern for counter-terrorism policing. Kerry's rearrest on suspicion of terrorism offences, even absent charges, places the case firmly within the counter-terrorism framework rather than treating it as an isolated homicide.

For investigators, the reopened Farage case offers both a potential evidentiary bridge to the Widdecombe murder and a test of whether the original 2025 inquiry missed something that, in hindsight, might have altered the trajectory of events. For the IOPC, it is a narrowly scoped conduct investigation that could have wider implications for how counter-terrorism units triage and resource lower-profile cases involving political figures. Both tracks will unfold against the backdrop of a criminal prosecution that has only just begun.
