This information is not collected centrally. Each Government Department, agency and non-departmental public body is responsible for setting its own communications priorities and outputs, and each Secretary of State is responsible to Parliament.
While no central figures are held on the total Government communications spend, figures for Departments’ expenditure through the Central Office of Information (COI) are shown in the COI Annual Report. Copies are available in the Libraries of the House. However these figures only provide a partial picture and do not distinguish between different advertising media.
