The UK intends to submit a request to Moscow to extradite two Russians suspected in the attack scout Sergei Skripal and his daughter with the help of a "Beginner", according to the Chronicle.info with reference to the channel 112.
The request will reignite the simmering diplomatic row with Russian Federation, which is certain to reject it, prompting another round of tit-for-tat diplomatic expulsions. The British investigation earlier reported that two of the alleged poisoner had to flee to Russian Federation.
Moscow has categorically denied all accusations over the novichok attacks.
Both survived, but on June 30 a British couple were poisoned by Novichok in a nearby town, one of whom, 44-year-old mother-of-three Dawn Sturgess, subsequently died.
The Home Office said that as a matter of long-standing policy and practice, the United Kingdom would neither confirm nor deny an extradition request had been made or received until such time as an arrest has been made in relation to that request.
However, the sources of The Times in the area of security confirmed that investigators are working to prepare the request for extradition.
"This is Litvinenko all over again".
Whitehall sources told the paper that authorities had identified two people they were ready to put on trial. Later, Sturgess died in the hospital, the other victims were discharged after treatment. The Russian constitution prevents the extradition of Russian citizens to another state.
Police believe the Novichok was smeared on the door of Sergei Skripal's house and perhaps discarded in a container that Sturgess's boyfriend Charlie Rowley then picked up. The diplomatic dispute escalated shortly after the Skipals' poisoning, with Britain and its allies expelling more than a hundred Russian diplomats in protest.
