A 28-year-old man has been charged with murder in connection the death of former MP Anne Widdecombe.
The Crown Prosecution Service authorised the charge against Joshua Kerry from Rotherham on Monday 20 July.
He is due to appear at Westminster Magistrate's Court on Tuesday morning.
Counter Terrorism Policing South East has been leading this investigation, supported by colleagues from Devon and Cornwall Police and from across the Counter Terrorism Policing network.
Officers were called to Widdecombe's home in Devon by the ambulance service at around 11:40 am on Thursday 9 July. She was found with serious injuries.
Kerry was initially arrested on Saturday 11 July, on suspicion of murder. He was then rearrested on suspicion of commission, preparation or instigation of acts of terrorism.
Police are still working to determine his motivations and any wider activity he may have been involved in.
Head of National Counter Terrorism Policing, Assistant Commissioner Laurence Taylor said: "Given Ann Widdecombe’s profile and the targeted nature of the attack, determining the motivation, including any possible political motivation, remains an active avenue of investigation for our detectives.
“As with all murder investigations, understanding the ‘why’ is a key part of our enquiries. This has been, and remains, a particularly intensive and complex investigation.
“Over the last week, our teams have gathered a huge amount of information, leading to over 800 lines of enquiry. Each of those needs assessing, carefully and thoroughly, and I ask that we are given the time to do that."
