To ask the hon. Member for Caithness, Sutherland and Easter Ross representing the House of Commons Commission, what (a) security and (b) immigration checks are made on casual staff working in Parliament.

The House Service ceased to engage casual workers last year. It does, however, engage staff supplied by agencies from time to time to meet unexpected demands and peaks of work.

Agency workers, in common with directly employed staff, are security cleared to Counter Terrorist Check (CTC) level and immigration/right to work checks are undertaken. The latter is done by requiring documentary evidence and in line with HMG’s Baseline Personal Security Standard.
