TWENTY-ONE people have been treated as a result of the ex-Russian spy poisoning, Wiltshire Police have confirmed.

They include an off-duty doctor and nurse who stopped to help the pair at the scene.

The doctor, who has not been named, was out shopping when she came across the pair.

She found Yulia Skripal, 33, slumped over a bench, unconscious, vomiting and having a fit.

Yulia had also stopped breathing.

The doctor got Yulia onto the floor and put her in the recovery position, before forcing her airway open so she could breathe.

Paramedics then arrived and took over the treatement.

The doctor who gave first aid was concerned she had been affected, but so far is said to be feeling fine.

Yulia and her father, former double-agent Sergei Skripal, are not said to be getting better and remain in a critical condition at Salisbury District Hospital.

The first officer on the scene, Detective Sergeant Nick Bailey, aged 38, of Salisbury CID, remains in a serious condition.
