We apologise to the Committee for making a mistake in the answers provided to these questions. The £28 million spend on external consultants mentioned in our answers was described as expenditure from May 2010. In fact the £28 million figure represents the total spend recorded with external consultants since the start of the programme through to the end of March 2013. This is information that has been previously published in response to Parliamentary Questions; see the answer of 24 January 2012, Hansard, column 167W and the answer of 17 June 2013, Hansard, column 528W.
