Chief Constable Commissioner for the Metropolis (Metropolitan Police Service)

The complainant has requested information about operational firearms and ammunition from the Metropolitan Police Service (the “MPS”). The MPS initially refused to disclose any information, citing section 31(1)(a) (Law enforcement) of FOIA. During the Commissioner’s investigation, the MPS revised its position. It disclosed some information but withheld the remainder, citing sections 31(1)(a) and 24(1) (National security) of FOIA. The Commissioner’s decision is that the MPS was entitled to rely on section 24(1) of FOIA to refuse to provide the remaining information. He does not require any steps.
