Prominent global Putin critics say British Prime Minister Boris Johnson's decision to suppress a parliamentary report into Russian influence is more evidence that the British political system is rotten when it comes to cracking down on Russian oligarchs.

The European Court ruled on Tuesday that the Russian government violated several articles in the European Convention on Human Rights over the course of its 11-month pre-trial detention and posthumous criminal conviction of Sergei Magnitsky.

Russia's influence reaches deep into the British establishment and successive UK governments have turned a blind eye to it, lawmakers were warned, according to multiple sources familiar with testimony given to a parliamentary inquiry.

'And then of course, there’s Brexit. In July 2020, the long-delayed Russia report published by the parliament’s intelligence and security committee presented a damning conclusion.'
