Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, pursuant to the contribution by the hon. Member for Croydon South on 14 September 2015, Official Report, column 787, what assessment has been made of the income received by public sector employers from the deduction of trades union dues at source.

The cost of administering a check off service, and therefore any charge agreed between the trade unions and the employer, varies across the public sector, depending on the legacy payroll systems in place.
