Absolutely categorically, Boris Johnson is a liar! Porton Down have confirmed that they don't know where the 'novichok' came from, yet Johnson stated that they had told him personally, the source was Russia. Will the PM now sack him for his continued un-ministerial behaviour? pic.twitter.com/1sZ522N3hj
