Recall that an ex-spy and his daughter were attacked in a British park with a view to killing at least the ex-spy. The weapon used was a nerve gas that’s only made in Russia. The investigation itself is pointing strongly at Moscow as the instigator of the murder attempt; although the investigation is not complete. Now Russia is refusing to cooperate in the investigation unless certain conditions are met.
Russian Foreign Minister Sergei Lavrov said that Moscow would only cooperate with the UK’s investigation into the nerve-agent poisoning of a former spy if London supplied the substance in question and opened up the probe to Russian officials.
