It is quite astonishing, but something useful appears to have come out of the United Nations committee on human rights - click here.
This looks like a reasoned and sensible critique of freedom of expression in the UK, identifying the main culprits - one each in respect of civil liability (libel), criminal liability (the promotion of terrorism offence), and Freedom from Information.
Unlike most of the output of "human rights" committees, these conclusions seem not to be counter-intuitive nor are they unrealistic.
That said, the UK has greater protection for freedom of expression than most other countries. But the position could still be better. This report may set out how this could be done.
