An investigation into the death of Ann Widdecombe is now being led by Counter Terrorism Police.

The former Conservative minister and later Reform UK spokeswoman was found dead at her home in Haytor on Dartmoor at about 11.40am on Thursday after sustaining serious injuries.

A 28-year-old white British man was arrested at an address in Rotherham, South Yorkshire, on Saturday evening, and is understood to remain in police custody.

Now, Counter Terrorism Policing South East confirmed they were leading the investigation after "new information and evidence has come to light".

Head of National Counter Terrorism Policing (CTP), Laurence Taylor, said: "Building on the progress made by our colleagues in Devon and Cornwall Police, we now have new information and evidence that means Counter Terrorism Policing is now leading the investigation.

"We are pursuing multiple lines of enquiry to establish the motivation for this attack. Our priority is progressing this investigation quickly, with all the capabilities we have available to us. If anyone has any information, please share it with the police.

"We would like to thank local communities, the wider public and the media for their ongoing support and patience, and would ask them to continue to support us in the next stage of the investigation."

CTP appealed for anyone who may have any information that could help the investigation.

Home Secretary Shabana Mahmood said: "This morning I have spoken to the head of CTP.

"Following new information and evidence, they are now leading on the investigation into the horrific murder of Ann Widdecombe.

"The police are pursuing multiple lines of enquiry to establish the motivation for this attack.

"I will be updating the House further this afternoon. My thoughts today remain with Ann’s family and friends, and all those who loved her."

On Sunday, there was a substantial police presence at a house in Byrley Road in the Kimberworth Park area of Rotherham outside an address linked to the suspect and more than 200 miles from the former minister’s home in Devon.
