To ask Mr Chancellor of the Exchequer, what research reports his Department has commissioned from external bodies between September 2010 and December 2014 has not been published; when each such report was commissioned; what the nature of the research commissioned for each such report was; from whom each such research report was commissioned; what the value of each such commission was; on what date each such report was received by his Department; for what reason each such research report has not yet been published; and when he plans to publish each such report.

The Department do not hold this information centrally. The information requested can only be provided at a disproportionate cost.
