Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of staff on the payroll of his Department who work in Westminster are (a) British nationals and (b) nationals of another country.

Many staff self-declare their nationality on the staff system. Evidence of nationality is checked at the point of recruitment into the Civil Service as part of wider pre-employment checks and copies of this evidence are held on file for the duration of the person’s employment and for a further two years after they cease working for the department.
