"The phone, internet and email records of UK citizens not suspected of
any wrongdoing have been analysed and stored by America's National
Security Agency under a secret deal that was approved by British
intelligence officials...
...an NSA
memo describes how in 2007 an agreement was reached that allowed the
agency to "unmask" and hold on to personal data about Britons that had
previously been off limits.
The memo, published in a joint investigation by the Guardian and Britain's Channel 4 News,
says the material is being put in databases where it can be made
available to other members of the US intelligence and military
community."
