Question to the Home Office:

To ask Her Majesty’s Government whether they have conducted any cost-benefit analysis of the counter-terorism security measures put in place over the last 20 years; and if so, what are the results of that analysis, who carried it out, and whether they will make it publicly available.

Government and the police undertake extensive work to assess terrorist threats and to ensure effective mitigations are in place. These measures are wide ranging and are implemented by numerous organisations, including across the private sector. The Government seeks to ensure that all appropriate and proportionate measures are implemented, and whilst mindful of cost-effectiveness, does not seek to put a price on the safety and security of the public.
