This information is not held centrally.
The transformational government strategy highlights three major change areas which focus on the citizen; joining up and increasing professionalism. Progress against these and other transformational activities are reported in the transformational government annual report. The report contains summary information about IT expenditure across government departments represented on the CIO Council (NB this is not the full IT expenditure across government and not all expenditure is related to transformational government strategy).
The reports for 2006 and 2007 can be found online on the CIO website at www.cabinetoffice.gov.uk/cio.aspx and copies are available in the Libraries of the House. The 2008 report is currently being drafted and will be published in due course.
