A “HITMAN and her” couple are being hunted by police over the poisoning of Sergei and Yulia Skripal.
Russian businessmen exiled in London have been asked if they can identify them.
Police said they appeared to be lovers aged 35-40 caught on CCTV canoodling close to the poisoned pair.
The suspects are understood to have left Britain hours after the Salisbury attack left the father and daughter fighting for life.
Anxious exiles on Vladimir Putin’s hitlist have been shown a picture of them.
Putin’s enemies have been told to stay vigilant and warned the pair may have been ordered to carry out multiple missions.
