Britain has said the type of nerve agent used in the Skripal attack was developed by the Soviet Union and could only have been produced by a state agency. The Telegraph reported that the woman's name is Dawn Sturgess, and the man is Charlie Rowley.
Russian chemical weapons expert Anton Utkin told Rossiya 1's "60 Minutes" programme that both the poisoning of Sergei and Yulia Skripal and the incident in Amesbury "could somehow be linked with some sort of narcotics". And Sergei Zheleznyak, deputy speaker of the State Duma, offered a novel theory for the new poisoning claims: British people who traveled to Russian Federation for the World Cup are developing "really positive emotions" about Russian Federation and the British government is doing whatever it can to remind them that the Kremlin is bad.
After spending weeks in critical condition, the Skripals slowly got better.
In addition to a "failed" Brexit and a "failed" economy, she is dealing with the uncertainty over Mr Trump's visit and the North Atlantic Treaty Organisation summit, he said.
"It's not just Amesbury, but also the nearby city of Salisbury, which has had areas shut off, like this park near where Sergei and Yulia Skripal were found unconscious earlier this year", said Al Jazeera's Sonia Gallego, reporting from Amesbury.
But after further tests, authorities declared a major incident and on Wednesday night counter-terror police assumed responsibility for the investigation after the Government's Porton Down laboratory concluded that the pair had been exposed to Novichok.
Skripal and his daughter have since left hospital.
Russian Federation responded by accusing Britain of playing "dirty political games" and said London would have to apologise.
Authorities initially believed the pair had taken a bad batch of heroin or crack cocaine. "But the very best thing we can do now is to give the police the space to carry out their investigation".
Making clear that the United Kingdom will "stand up to the actions that threaten our security", he added: "It is completely unacceptable for our people to be either deliberate or accidental targets, or for our streets, our parks, our towns, to be dumping grounds for poison".
A spokesman for Public Health England (PHE) said "it is not believed that there is a significant health risk to the wider public". They were called back later that day when Mr Rowley, 45, also fell ill. Hobson said he went to Rowley's house on Saturday as Sturgess was being taken to hospital and stayed with him for several hours until he too began to complain of feeling ill.
Salisbury is about 8 miles from where Sturgess and Rowley lived.
The UK's top counter-terrorism officer confirmed the couple's condition today, four days after they were rushed to hospital.
