The complainant requested both the titles of and the actual reports held by The Extremism Analysis Unit. The Home Office refused to provide any of the requested information, citing the following FOIA exemptions: sections 24(1) - national security, 27(1)(a) and (c) - international relations, 31(1)(a) – law enforcement, 35(1)(a) – formulation of government policy, 38 – health and safety and 40(2) – personal information. The Home Office applied sections 24, 31 and 35 to the withheld information in its entirety. The Commissioner’s decision is that the withheld information was exempt from disclosure under section 24 of FOIA. As he has found section 24(1) to apply to all the withheld information, the Commissioner has not deemed it necessary to consider the Home Office's reliance on the remaining FOIA exemptions. No steps are required as a result of this notice.
