Figures from the Office of Government Commerce (OGC) has published figures on how much the government spent on IT, networking and related costs last year. This does not include people costs.
The total spend on IT was £7.57bn and outsourcing was the biggest single chunk of spending at £2.33bn.
See the full breakdown in this article.
It is good that the government knows what it spends on IT and networking but the total spend including people costs is much higher. In fact part of the problem facing the government as it tries to bring down costs is that it doesn't actually know how much it spends in total.
Apparently it thinks it is between £13bn and £20bn. Mind the gap. I wouldn't mind it.
