Re: It's ID cards again isn't it?
"trusted private sources"
As in "Show me the money!"
or "Give me the data you hold."
Pick one, two or both.
National Registration Act: Repealed 21 Feb 1952. The National Registration number persisted, being used within the National Health Service, for voter registration, and for the National Insurance system.
The records created under the National Registration Act are held by The National Archives but were not freely accessible to the public for many years. From 2010, subject to restrictions to safeguard the privacy of people who are or may still be living, information could be obtained from the NHS Information Centre about specific individuals for a fee.
The National Archives has now entered into an agreement under which the original documents for England and Wales have been digitised and scanned and are available (subject to privacy restrictions) on the subscription-based Findmypast and Ancestry.com websites.
"subject to privacy restrictions" - see top of comment.
HMG is supposed to be on our side.
