Ministers in Tony Blair’s government were advised to use Post-it notes for sensitive messages to avoid having to release them under new Freedom of Information, according newly-released official files.
The Labour government had originally passed the Freedom of Information Act in 2000 but as the full implementation date approached on January 1 2005 there was growing disquiet among ministers and senior officials at the implications.
Presumably not every scrap of paper has to be kept, and this fell into a loophole or grey area.
I would guess they thought it was a loop hole but were wrong.
