The editor of Britain’s Guardian newspaper claimed “a great victory for free speech” on Tuesday in a battle over the right to report the proceedings of parliament after political blogs and thousands of Twitter users flooded the internet with details of a gagging order.

The Guardian and other newspapers, including the Financial Times, had been preparing to go to the High Court to challenge the so-called super injunction, which had the effect of preventing reports on an MP’s question about legislation to protect whistleblowers and press freedom even though it had been mentioned in a House of Commons order paper and online.
