Former Russian spy Sergei Skripal is "improving rapidly" and is "no longer in a critical condition" following a nerve agent attack in Salisbury last month, the hospital treating him said in a statement on Friday.
Christine Blanshard, medical director at Salisbury District Hospital, said Skripal, 66, was responding well to treatment and his condition was improving.
The news comes a day after Skripal's daughter Yulia, 33, who was also poisoned in the attack, released her first public statement after regaining consciousness last week, thanking those who had treated her and her father and all those who had sent "messages of goodwill."
"As Yulia herself says, her strength is growing daily and she can look forward to the day when she is well enough to leave the hospital," Blanshard said Friday. She gave no indication when Yulia or her father could be released.
Yulia and Sergei Skripal were found slumped on a bench at an outdoor shopping precinct in the English city of Salisbury on March 4.
The British government believes they were poisoned with a Russian-made nerve agent, Novichok, but Russia denies involvement.
Detectives revealed last week that they believe the Skripals first came into contact with a nerve agent at the former spy's home and that the highest concentration of the substance had been found on the front door.
The incident has led to a spiraling diplomatic dispute between the two countries. The UK and its allies have expelled scores of Russian diplomats, triggering retaliatory expulsions by Russia.
At the United Nations Security Council meeting on Thursday, Vassily Nebenzia, Russia's UN envoy, called the allegations of Russian culpability a "fake story" and said the UK was "playing with fire and they will be sorry."
The British government insists that only Russia had the capability to carry out the attack.
The UK Foreign Office said Thursday that Yulia Skripal has so far declined the Russian Embassy's offer of consular assistance following the attack. The Russian Embassy in the UK has repeatedly said it requested consular access to Yulia and Sergei Skripal, but that it had been "denied."
