Question to the Home Office:

To ask the Secretary of State for the Home Department, if she will list the number of people on the terrorist watch list by (a) nationality, (b) sex, (c) religion and (d) immigration status.

It is longstanding policy not to discuss either the specific information held on any security-related watchlist, the source of the information or how it is used.

To do so would be counterproductive and harmful to the national security of the UK.
