Craig Murray, former British Ambassador to Uzbekistan, debunks the 'Russia poisoned Skripal' story. He writes:
'It is a scientific impossibility for Porton Down to have been able to test for Russian novichoks if they have never possessed a Russian sample to compare them to. They can analyse a sample as conforming to a Mirzayanov formula, but as he published those to the world twenty years ago, that is no proof of Russian origin. If Porton Down can synthesise it, so can many others, not just the Russians.'
