Anti-radicalisation scheme found to have made series of errors in case of Ali Harbi Ali, who went on to murder MP

The Prevent scheme made a series of errors in its handling of the man who went on to murder the Conservative MP David Amess, a review has found.

Ali Harbi Ali was convicted of Amess’s murder in 2022 when he was 26. He had been referred to Prevent in 2014 by his school and his case was adopted amid concerns he could have an interest in violent Islamism.
