Sir David Amess killer left Prevent too quickly, review says

Sir David Amess’s killer was exited from the government’s Prevent anti-terror programme “too quickly” and its handling of him was “sub-optimal”, a review says.

Ali Harbi Ali, who killed the Southend West MP in 2021, was referred to the Prevent programme for two years, security minister Dan Jarvis has told the Commons.

He said: “The perpetrator had previously been referred to the Prevent programme and subsequently to the specialist Channel programme between 2014 and 2016, between five and seven years before the attack took place.

“The perpetrator of the attack on Sir David became known to Prevent in October 2014, when he was referred by his school after teachers identified a change in his behaviour.”
