By Craig Murray:
 Evidence submitted by the British government in court today proves, 
beyond any doubt, that Boris Johnson has been point blank lying about 
the degree of certainty Porton Down scientists have about the Skripals 
being poisoned with a Russian “novichok” agent.
Yesterday in an interview with
 Deutsche Welle Boris Johnson claimed directly Porton Down had told him 
they positively identified the nerve agent as Russian:
 
You argue that the source of this nerve 
agent, Novichok, is Russia. How did you manage to find it out so 
quickly? Does Britain possess samples of it?
