Wiltshire officer who had displayed signs of low exposure to novichok brings total number of initial victims to four

A second police officer was poisoned in the Salisbury novichok attack, Scotland Yard has confirmed, after traces of the deadly nerve agent were discovered in a blood sample.

The poisoning of former Russian spy Sergei Skripal and his daughter Yulia, both of whom survived after fighting for their lives, also left a policeman critically ill after he searched their home.
