John Hemming, a Liberal Democrat MP in the UK, has said it would be impractical to imprison 75,000 Twitter users who have named footballer Ryan Giggs as having an injunction over an alleged affair with Imogen Thomas, a British reality TV star.

Addressing parliament on Monday, Hemming said: "With about 75,000 people having named Ryan Giggs on Twitter, it is impractical to imprison them all."
