As the head of counter-terror police has said, digital forensic examinations are one of the lines of inquiry the force is pursuing in its investigation.

Digital forensics is a branch of forensic science that looks at identifying, acquiring, processing, analysing and reporting on electronically stored data, according to Interpol.

It says the main aim of the digital forensics process is to extract data from an electronic evidence, turn it into intelligence that police can use, and present it for prosecution.

Interpol notes that electronic evidence "is a component of almost all criminal activities", so digital forensics plays a central role in law enforcement investigations.

This electronic evidence can be collected from a variety of sources - including computers, smartphones or remote storage.

Ann Widdecombe gave a pre-recorded radio interview about 20 minutes before police believe she was attacked on Wednesday 8 July.

The former Conservative minister, later a Reform UK spokeswoman, spoke to British Christian radio station TWR-UK for about nine minutes via video link, but the interview wasn’t broadcast.

The station later shared part of the recording with Times Radio, which first aired the interview on Tuesday.

In the interview, she spoke about her support for Reform UK leader Nigel Farage.

Here's a recap of what Counter Terrorism Policing has said just now:

• The killing of Ann Widdecombe is a "targeted attack"
• Detectives have obtained a warrant to hold the 28-year-old suspect for up to seven days under the Terrorism Act
• Detectives are still working to understand the motive
• A counter-terrorism investigation is "running in parallel" to the murder investigation
• The suspected murder "has not been declared a terrorist incident at this stage"
• The investigation is "complex", with multiple lines of inquiry, including "digital forensic examinations"

Counter-terror police were also asked if there was a relationship between the first person arrested and then released, and the current suspect in custody.

Assistant Commissioner Laurence Taylor says: "The first individual that was arrested and then released, as Devon and Cornwall police have said, they do not have any involvement in this matter."

He also says that they are not involved in the investigation.

As a reminder, Devon and Cornwall Police said on Thursday that they had arrested a 26-year-old white British man on suspicion of murder, but on Saturday they said he had been released.

Later on Saturday, police announced the arrest of a 28-year-old white British man on suspicion of murder. The 28-year-old was re-arrested on Monday on suspicion of commission, preparation or instigation of acts of terrorism, after the investigation was taken over by counter-terror police.

In the on-camera statement, Head of Counter Terrorism Policing Assistant Commissioner Laurence Taylor says that "extensive searches have taken place at an address in Rotherham", where the 28-year-old white British man was arrested.

He says there are "multiple lines of inquiry" that police are "pursuing expeditiously, including digital forensic examinations".

Taylor says he wants to remind the public that investigations like this are "complex" and "new information can emerge".

More information will be released when it is available and appropriate, he says.

Taylor said he could not comment when asked if the suspected murder of Ann Widdecombe was an attack on Reform UK.

"I don’t want to rule out anything," he said. He also would not comment on whether they were investigating whether a foreign state was involved.

"We are working through what the motivation for the attack currently is," he said. "At this stage I wouldn’t want to comment on the motivation."

He also said he cannot comment on details about the planning and preparation of the suspected attack.

He said the counter-terrorism investigation is "running in parallel to the murder investigation" and that "we are investigating terrorism offences".

But he would not comment on whether that means the suspect potentially committed terrorism offences separate to the alleged murder case, or whether any other politicians were potential targets.

Taylor also said that, at this stage, the suspected murder of Ann Widdecombe "has not been declared a terrorist incident".

"This is a murder investigation following a brutal attack on a 78-year-old woman in her own home."

There has been a "deeply distressing impact on Miss Widdecombe’s family", he adds.

The killing of Ann Widdecombe was a "targeted attack" and detectives are still working to understand the motive, counter-terrorism police say.

Head of Counter Terrorism Policing, Assistant Commissioner Laurence Taylor, gave an update on the Ann Widdecombe investigation at New Scotland Yard this afternoon.

He said there is a "limit" to the details he can provide given it is a live murder investigation but "it is clear this was a targeted attack".

He added: "We are working to understand the planning and preparation and the motivation that sits behind the attack."

He said detectives have obtained a warrant of further detention and can now hold the suspect for up to seven days under the Terrorism Act.

Yesterday, as Home Secretary Shabana Mahmood made her statement in the Commons, MPs from across the political spectrum shared their condolences.

Mahmood remembered Widdecombe as "forthright and fearless" and someone who "thought seriously about ideas but did not take herself too seriously".

Shadow home secretary Chris Philp said "we will all remember Ann fondly" and described her as a public figure who was "always formidable, always charming, and always entertaining".

Reform UK MP Richard Tice described Widdecombe as "a colossus" in public and political life, praising her for an "incredible work ethic".

Liberal Democrat MP Max Wilkinson said while he didn't always agree with Widdecombe, her style of presenting arguments was "compelling".

Scottish National Party MP Pete Wishart called Widdecombe "a larger than life political figure".

We have just heard an on-camera statement from the Crime Commissioner for Devon and Cornwall Police Alison Hernandez.

It was a readout of the same statement we published earlier, where she says she is "confident that Devon and Cornwall Police has provided a substantial and professional response to Ann Widdecombe’s death".

She did not take questions from the media.

Ann Widdecombe was born in Bath, Somerset, in 1947.

She went on to study Latin at Birmingham University, then philosophy, politics and economics at Oxford University.

Her political career spanned several decades, having served as a Tory MP for Maidstone in Kent from 1987 to 2010.

She worked as a Home Office and employment minister in John Major's government between 1994 and 1997.

After Parliament, an unlikely showbusiness career awaited the former minister. She appeared on various prime-time television shows, including Strictly Come Dancing in 2010 and Celebrity Big Brother in 2018.

A staunch supporter of the UK's departure from the EU, she became an MEP for the Brexit Party, representing South West England in the European Parliament between 2019-2020.

In 2023, she joined Nigel Farage's Reform UK, after the party changed its name from the Brexit Party, where she served as immigration and justice spokesperson.

As mentioned, Devon and Cornwall Police and Crime Commissioner Alison Hernandez has defended the force, as "there's been some commentary about the way Devon and Cornwall police have communicated during the early stages of this case".

It follows comments from Assistant Chief Constable Matt Longman, who told a news conference on Friday the force had ruled out terrorism and had no information to suggest Widdecombe's death was a "politically motivated crime".

But on Monday it was announced counter-terrorism police would take over the investigation. A 28-year-old suspect - who was originally arrested on suspicion of murder on Saturday - was re-arrested on suspicion of commission, preparation or instigation of acts of terrorism.

Hernandez says "it is not unusual" in a fast-paced investigation for the nature of the inquiry to change as more information comes to light.

We can now bring you the full statement from Devon and Cornwall Police and Crime Commissioner Alison Hernandez:

“As Police and Crime Commissioner, I have personally spoken to the Head of Counter Terrorism, Laurence Taylor, to thank him for the resources he offered early on, and to seek the reassurance that there has been a smooth handover of the investigation.

"There’s been some commentary about the way Devon and Cornwall police have communicated during the early stages of this case but, as the Home Secretary said yesterday, it is not unusual that in a fast-paced investigation, more information comes to light that changes the nature or the character of what the police are dealing with.

"Since the beginning of this investigation, I have been briefed by the Chief Constable regularly, and I am confident that Devon and Cornwall Police has provided a substantial and professional response to Ann Widdecombe’s death.

"I am particularly grateful to members of the public, who have provided information and assisted officers in progressing the investigation.

"My thoughts remain with Ann’s family and friends. I have been touched by the stories I have heard from those who lived closed to her on Dartmoor. Whatever you thought of her politics, Ann was an exceptionally likeable character.

"When I visited the scene on Sunday, I was impressed by the efforts being made by the police to speak to residents and address their very understandable concerns.

"I am sure the impact of this major operation has meant that some people have had to wait longer than they would expect for routine services, or have not yet had their issues resolved.

"I have been assured officers and staff will be returning to business as usual over the coming days, which are also expected to be particularly busy with two final legs of the World Cup and the start of school holidays.”
