Killer of MP Sir David Amess was 'exited' from Prevent 'too quickly', review finds

The man who killed Conservative MP Sir David Amess was released from the Prevent anti-terror programme "too quickly", a review has found.

Sir David was stabbed to death by Islamic State (ISIS) supporter Ali Harbi Ali during a constituency surgery at a church hall in Leigh-on-Sea in October 2021.

The killer, who was given a whole-life sentence, had become radicalised by ISIS propaganda and had been referred to the anti-terror programme Prevent before the attack.

His case had been closed five years before, after just one meeting for coffee at a McDonald's to deal with his interpretation of "haram" (forbidden under Islamic law), as well as texts and calls with an "intervention provider".

Despite Prevent policy and guidance at the time being "mostly followed", his case was "exited too quickly", security minister Dan Jarvis told the House of Commons on Wednesday.

Following the publication of a review into Prevent's handling of Southport child killer Axel Rudakubana earlier this month, Mr Jarvis said a Prevent learning review into Sir David's killing would be released this week in a commitment to transparency over the anti-terror programme.

However, Sir David's daughter, Katie, has dismissed it as a "paper exercise" with no proper accountability and is pushing for a "full public open inquiry".

Matt Juke, head of counter-terrorism policing, said it's clear the management and handling of Ali's case by Prevent "should have been better" and it is "critical" the review is acted on "so that other families are spared the pain felt by the loved ones of Sir David".

The review found:

• Ali was referred to Prevent in 2014 by his school after teachers said his demeanour, appearance and behaviour changed from a previously "engaging student with a bright future" with aspirations to be a doctor to failing his A-levels and wanting to move to a "more Islamic state because he could no longer live among unbelievers"

• Prevent quickly took his case on and he was referred to Channel, part of the programme that aims to prevent involvement in extremism

• He was "exited from Prevent too quickly", Mr Jarvis said, just five months later "after his terrorism risk was assessed as low"

• A review by police 12 months after he was released from Prevent "also found no terrorism concerns" and the case was closed. This was not uploaded for eight more months due to an "IT issue"

• People released from Prevent are meant to have a review at six and 12 months

• The assessment of Ali's vulnerabilities "was problematic and outdated" as it did not follow the proper procedure, which led to "questionable decision-making and sub-optimal handling of the case"

• Ali's symptoms were prioritised over addressing the underlying causes of his vulnerabilities - and support provided did not tackle those issues

• Record keeping of decisions, actions and rationale was "problematic, disjointed and lacked clarity"

• The rationale for certain decisions was "not explicit"

• Ali's school was not involved in discussions to help determine risk and provide appropriate support - they were only called once to be told the "matter was being dealt with"

• A miscommunication led to only one intervention session being provided, instead of two.

The review found most of the failures in Ali's case would not be repeated today as the guidance and requirements are much clearer.

It said referrers, in Ali's case his school, are kept informed and engaged, and different departments and agencies - not just police - have clear roles.

Which records need to be kept is now clear and guidance for detecting underlying vulnerabilities has changed and would have made a difference, the review added.

It said a Prevent "intervention provider" met Ali at a McDonald's to deal with his understanding of "haram" (forbidden under Islamic law).

No risk assessment was made but they suggested one more meeting, however a breakdown in communication between the police and the provider meant there were no more meetings.

Training for providers is "substantially different" now and the review says this would not be repeated today, with the provider in question saying the process is "a completely different one today".

However, the review said there are still problems - not just in Ali's case - with the Vulnerability Assessment Form, an "incredibly complex document that is vital to Channel" and the progression of a case.

It also found a more recent decision by the College of Police to only hold Prevent case data for five years "may prove to be problematic" and if Ali's case material had been deleted under that ruling "it would have been nigh on impossible to conduct this review".

'Dad deserved better from friends in parliament'

Katie Amess welcomed Wednesday's announcement of a public inquiry into the Nottingham attacks but said every victim failed by Prevent deserved the same.

She told The UK Tonight with Sarah-Jane Mee she had been briefed on the findings of the learning review last year.

Ms Amess said she had to sign "a contract to say I wouldn't tell anybody what was in it otherwise I'd go to prison or be fined".

She dismissed the review as woefully insufficient and said it was just put together from existing paperwork and email logs.

The 39-year-old, who is taking legal action against Essex Police and the Home Office, told Sky News her father deserved better from his "friends" in parliament after the decades he served as an MP.

Ms Amess also criticised Yvette Cooper's reticence to approve a public inquiry as she was not in office when her father was murdered. The MP's daughter said other inquiries had been signed off by home secretaries in similar circumstances.

"I want to know what is being covered up and why they're not committing to an inquiry for myself and other victims," she told Sky News.

Ms Amess said the information that's emerged so far vividly shows the weakness of the Prevent programme, with "no clear form of communication between police and Prevent and other channels".

She told Sarah-Jane Mee: "He [Ali] even stood up in his trial and made a mockery of Prevent; he said all you need to say is 'I'm not a terrorist and they stop following you' - what message does that send?"
