Is this the end for Britain as a centre for libel tourism? | Media | The Guardian: "In one case, Pavel Karpov, a retired Russian policeman, had been suing Bill Browder, a naturalised British businessman, for claiming that Karpov had a role in the death of the anti-corruption campaigner Sergei Magnitsky. In the other, a Serbian entrepreneur called Stanko Subotic was pursuing several Balkan publications over allegations that he was involved in organised crime. Both cases have now been dismissed, however, on the grounds that the plaintiffs have no real reputation in England to defend." 'via Blog this'
