Treasury Ministers have received a number of representations on various aspects of the administration of the tax credits system. In particular the Government have responded to the sixth report of the Treasury Committee, session 2005-06, on the administration of tax credits, on 8 November 2006 and I refer the hon. Member to the debate on that report on 15 March 2007, Official Report, columns 141-84WH. In addition, Treasury Ministers regularly report to the House on the operation of tax credits.
