**Corporations**
[usaspending.gov](http://www.usaspending.gov/) – government initiative to show how much is being spent with corporations. Could we don in the UK? Special Purpose Vehicles and PFI could be a rich journalistic area, as could charities. Every project over £100k has to be advertised, so you could start reverse-engineering that. It’s not centrally stored right now, though, so you’d have to make FOI requests to each department. 
[Companies Open House](http://ukcompani.es/) – an effort to make Companies House data searchable at all times and permalinkable.
**Lawyers**
