Some more quotes from the report
"The Department holds £4.2 billion of inventory that has not moved in over two years and a further £2.4 billion of holdings sufficient to cover five years of use. However it spent £1.5 billion in 2009-10 and 2010-11 on consumable inventory that it has not used"
"During 2010 and 2011, these central projects identified £1.4 billion (gross) of inventory that could be sold or destroyed."
"At the end of November 2011, 20 per cent of inventory management posts were vacant, and of those staff in post, 13 per cent had not obtained the appropriate qualifications"
"However, the root cause of the excess stock is that management and accountability structures fail to provide the incentives to drive cost-effective inventory management."
