CEP Senior Advisor Ian Acheson writes: "Robert Jenrick is continuing to annoy all the right people. This weekend he turned his focus to the appalling attacks on front line prison staff, including by terrorists, that have left dozens of wounded, maimed and traumatised officers struggling to contain the threat in our High Security prisons.

Jenrick asked me to produce a rapid analysis of the current terror threat drawing on my experience as a former government reviewer of the UK threat and my work around the world on managing highly dangerous people. While this paper could not have access to the ongoing official review, I did think I had enough expertise to add to the debate. The criminal justice commentariat were apoplectic. Why?"

CEP Senior Advisor Ian Acheson: "I was asked by the shadow justice secretary to undertake a rapid review of the current threat to prison officers in general and those maimed by terrorists in particular. I was given no terms of reference, no steer and no interference at all in my full analysis which will be published online this afternoon. Jenrick is a politician for a party I used to be part of. Notwithstanding the politics, I believe him to be sincere in his concern about public servants who are closer to being murdered on duty by fanatics than at any time in the last 25 years."
