UK police have arrested a man on suspicion of murdering Ann Widdecombe, after the 78-year-old former minister was found dead having "sustained serious injuries".
Police said a 26-year-old British man had been arrested in Newton Abbot, a town about 15km from Widdecombe's home in rural southwest England.
Devon and Cornwall police assistant chief constable Matt Longman said there was no information to suggest the murder was related to terrorism or had a political motive.
Widdecombe was well known for her socially conservative views, first as a junior minister in Conservative prime minister John Major's 1992-1997 government and later as an immigration and justice spokeswoman for Nigel Farage's populist Reform UK.
She also found fame outside politics after starring in TV shows Strictly Come Dancing and Celebrity Big Brother.
Police said officers were called to Widdecombe's home shortly after midday on Thursday, where she was found dead.
Forensic examinations at the property were ongoing, they said.
Prime Minister Keir Starmer paid tribute to "Ann's dedication during her many years of public service".
He said that it was a moment to "rise above any political differences" and added he had spoken to his expected successor Andy Burnham, Conservative leader Kemi Badenoch and Reform UK leader Farage about the case.
Following the announcement of her death, and before details of the murder inquiry were announced, former colleagues from both the Conservative and Reform UK parties paid tribute to her.
Farage said he was "deeply, deeply upset" by the nature of Widdecombe's death.
He added: "Rest in peace, Ann. A remarkable, principled woman, and a truly dreadful way to die, and a terrible reflection on modern Britain.
"And I do fear that for anybody in public life, or especially the political space, things have become even more dangerous to them."
Commons Speaker Sir Lindsay Hoyle, who established the Speakers' Conference in 2024 to examine the security risks faced by MPs, said: "I'm deeply shocked to learn of the circumstances around Ann's death.
Former Conservative prime minister Boris Johnson called her "a heroic Brexiteer and a great speaker who could move Tory audiences to such ecstasy that she was a very hard act to follow."
Widdecombe, who appeared on TalkTV on Wednesday, lived in Haytor, near Newton Abbott in Devon.
UK Home Secretary Shabana Mahmood urged the public not to speculate, describing the circumstances as "extremely distressing".
In a post on X, Mahmood said: "I am deeply saddened to hear of the death of Ann Widdecombe. The circumstances of her death are extremely distressing and my thoughts are with Ann's family and loved ones".
"I urge everyone to avoid speculation and allow the police investigation to progress."
