CCTV footage has emerged of what appears to be former Russian spy Sergei Skripal and his daughter just moments before they were found poisoned on a bench.

Video from inside a nearby restaurant appears to show the 66-year-old walking with two women, one of whom is believed to be his daughter Yulia, 33, in the city of Salisbury, Wiltshire.

The pair remain critically ill in intensive care after they were found unconscious just yards away from where they were seen on camera.

Detectives believe they were targeted with a “rare nerve agent“ in an assassination attempt.

Counter-terror officers reportedly seized a copy of the CCTV, first published by The Mirror, to aid in the investigation into the poisoning.

The second woman in the footage has not yet been publicly identified.

The trio were seen walking down an alley at 4:08pm, close to the Zizzi restaurant where they had eaten. At 4:15pm, a police car can be seen speeding down the alleyway in response to a 999 call. At 4:18pm, a first-responder ambulance car arrived on scene.

A Scotland Yard spokesperson said they were unable to comment on an ongoing investigation.

It comes after up to 180 military personnel were being deployed to Salisbury to aid the ongoing investigation, police said.

The national counter-terror policing network, which is leading the probe, said it had requested help to remove “a number of vehicles and objects from the scene in Salisbury town centre as they have the necessary capability and expertise”.

A spokesperson said: “The public should not be alarmed and the public health advice remains the same. The military has the expertise and capability to respond to a range of contingencies.
