Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how much has been spent by each (a) Government department and (b) non-departmental public body on (i) focus group research, (ii) opinion polling and (iii) other forms of opinion research in each of the last 20 years.

The Treasury does not hold research spend for other Governments Departments. However, the Government routinely publishes details of all contracts over £10,000 on Contracts Finder.

As has been the case under successive administrations, any Government research, polling or analysis would be for official use.
