[holding answer 22 January 2009]: The Child Maintenance and Enforcement Commission is responsible for the child maintenance system. I have therefore asked the Child Maintenance Commissioner to write to the hon. Member with the information requested.
Letter from Stephen Geraghty, dated 11 February 2009:
In reply to your recent Parliamentary Question about the Child Support Agency and the Child Maintenance and Enforcement Commission, the Secretary of State promised a substantive reply from the Child Maintenance Commissioner. The Child Support Agency is now the responsibility of the Child Maintenance Enforcement Commission.
You asked the Secretary of State for Work and Pensions, how many staff were employed in (a) the Child Support Agency and (b) the Child Maintenance and Enforcement Commission in each quarter since March 2008; and how many are expected to be employed in each quarter to December 2012. 
The Child Maintenance and Enforcement Commission took responsibility for the Child Support Agency from 1 November 2008, at which point all staff employed by the Agency transferred to the Commission. The table below sets out the number of full-time equivalent employees directly employed by the Agency and the Commission in the last four quarters and the current estimate for the quarter ending March 2009, rounded to the nearest hundred.
March 2008 June 2008 September 2008 December 2008 March 20091 Agency 9500 9500 9400 — — Commission — — 5 9300 8900 1 Estimated
The Child Maintenance and Enforcement Commission's projected level of staffing for the remaining two years of the current spending review period will continue to be kept under review to ensure that the Commission lives within its allocated funding.
I hope you find this answer helpful.
