Police have arrested a man after an alleged threat to shoot Nigel Farage, in the tense aftermath of the reported killing of former Conservative MP Ann Widdecombe in what is described as a targeted attack. The case matters because it appears to have intensified concerns about the safety of high-profile politicians and the wider risk of politically motivated violence in Britain. The article presents the arrest as part of a rapidly developing security story involving both a murder investigation and a separate threat against a senior political figure.

The key details available in the text are limited, but the report says Widdecombe was killed and that police treated the incident as a targeted attack rather than a random event. It also says a man was arrested over threatening to shoot Farage, and refers to a dispute over politicians' security after Farage claimed Sir Keir Starmer had described Widdecombe's death to him as a burglary that had gone wrong. Beyond those points, the supplied article text does not provide fuller information such as the suspect's identity, exact timing, location, or formal charges.
