The Shutting Down of British Blogs

For weblogs class we have been told to investigate about the shutting down of some British blog sites because of libel and asked what laws were broken because of what was said in Craig Murray’s political blog about Alisher Usmanov’s character. He was motivated to do so because of Mr Usmanov’s investment in arsenal football club. The statements in his blog were about the torture of prisoners for information in Uzbekistan. This next paragraph was copied from wikipedia.
He wrote in 2003 In a letter to his employers, in response to a speech by George W. Bush, "when it comes to the Karimov regime, systematic torture and rape appear to be treated as peccadilloes, not to affect the relationship and to be downplayed in the international fora ... I hope that once the present crisis is over we will make plain to the U.S., at senior level, our serious concern over their policy in Uzbekistan.
This shows his opinion about Mr Usmanov and here is a link to some of Craig Murray’s blogs that have been reposted Craig's reposts
And even when Mr Usmanov’s lawyers threatened to sue the blog sites if they didn’t take all the posts off Craig Murray welcomed his lawyers to come after him which the never pursued any case against him which in my personal opinion looks a bit strange. So this leads me to believe there is maybe truth in what Craig Murray is saying.
