Counter-terror police have taken over the inquiry into the collapse of a former Russian double agent and his daughter on a Salisbury park bench.
Sergei Skripal and his daughter both remain in critical condition in hospital tonight after being exposed to an unknown substance.
Boris Johnson told the Commons today that he is not pointing fingers, but warned that Britain will respond “robustly” if evidence of state responsibility for the Salisbury incident emerges.
For their part, a spokeswoman for the Russian Foreign Ministry dismissed Mr Johnson’s comments as “wild”.
