LONDON — The killing of former British politician Ann Widdecombe is now being considered an act of terror, police said Monday.

The 28-year-old man suspect, who was first arrested on suspicion of murder, was rearrested on suspicion of commission, preparation or instigation of acts of terrorism, Counter Terrorism Policing South East said.

Police originally had said it was not believed to be a terrorism-related crime or politically motivated.

“We now have new information and evidence that means Counter Terrorism Policing is now leading the investigation,” Head of National Counter Terrorism Policing, Laurence Taylor, said. “We are pursuing multiple lines of inquiry to establish the motivation for this attack.”

Widdecombe, 78, was found dead last week in her isolated rural home in a southwest England village. Police did not disclose a cause of death, saying only that she had sustained “serious injuries.”

The death sent shock waves through British politics, where Widdecombe had been a prominent voice for decades, known for her robust personality and socially conservative views opposing abortion and the expansion of LGBTQ+ rights.

The suspect, who has not been named because he hasn’t been charged, was arrested Saturday in South Yorkshire county in northern England, more than 200 miles (320 kilometers) from the village of Haytor on the edge of Dartmoor National Park, where Widdecombe was found dead Thursday.

Police said they believe Widdecombe was attacked at around 12:30 p.m. on Wednesday. Concerns were raised for her after she failed to appear for a scheduled TV interview on Wednesday afternoon.

Widdecombe was a lawmaker in the House of Commons as an MP from 1987 to 2010, serving in roles including prisons minister in Prime Minister John Major’s 1990s Conservative government.

Widdecombe found fame after leaving Parliament as a contestant on the reality television shows “Strictly Come Dancing” and “Celebrity Big Brother.”

She later joined the Brexit Party, briefly serving as a member of the European Parliament before Britain left the European Union in 2020. Most recently, she joined the anti-immigration Reform UK party, often appearing in the media as a spokesperson.

Friends and colleagues contrasted her pugnacious political statements with her personal kindness and good humor.
