the monies wasted on NPfIT, botched MoD procurements, etc etc. - ah, yes :) And the multi-million-pound IT systems that never work, including the one for the new benefits system which doesn't even work in testing. The £1-a-sheet copy paper and overpriced notepads sold to public bodies all over the country, the bulk NHS supplies that are more expensive than buying them individually ... not to mention the pilferage, wastage and cock-ups. It's a joy to behold.
I met someone who was involved in setting up new computery stuff at Westminster. They'd already spent millions on consultancy, software design, specifications, etc, etc. They hadn't laid in enough power to support the system 
Note: The above doesn't only apply to this administration, it's been going on for ages. But It does somewhat grate when those same incompetents are telling us how to manage our personal finances.
