The ICO is a bureaucrat with responsibility for enforcing the Data Protection Act. There is a small amount of overlap with the Surveillance Commissioner who oversees all surveillance, especially under RIPA (regulation of investigatory powers act).

The ICO is reasonably good - I don't get any (personal) junk telephone calls or junk mail because of our laws about how companies handle my data. (This seems like a trivial example now I've typed it! But it did mark a clear difference between before and after ICO).

The website and reporting is much better than it used to be. ("Please download, print, and complete this MS Word document, then post it to this address")
