Counter-terrorism police have said they believe the murder of former MP Ann Widdecombe was a "targeted attack".
The 78-year-old politician was found dead at her home on Dartmoor last Thursday after sustaining serious injuries. A 28-year-old man remains in police custody for a third day after detectives were granted additional time to question him.
Widdecombe, a devout Catholic, had recorded an interview with Christian radio station TWR-UK via Zoom at 11.54am on Wednesday, around 20 minutes before police believe she was killed.
During the interview, she discussed Reform UK leader Nigel Farage's decision to trigger a by-election in his Clacton constituency.
Assistant Commissioner Laurence Taylor, head of Counter Terrorism Policing, said: "It is clear that this was a targeted attack.
"We are still working to understand the extent of any planning or preparation and the motivation that sits behind that attack."
