FOI.gov.uk - Freedom of Information is a great site for knowing what's legally allowed from the access point of view.
The Data protection act governs dos' & don'ts, an easier FAQ read can be found on
DCA - department for Constitutional Affairs website
I believe new laws have just come into effect for the
ICO - Information Commissioners Office (their website seems to be having a weekend glitch !!) -
news item from Computerweekly.co.uk
Handling and other
Requirements - from standards.dcsf.gov.uk
Please feel free to use the search facility on here as there are other threads that mention confidentiality and disclosure.
