BORIS JOHNSON has pledged to "stamp out" the use of chemical weapons after global inspectors confirmed a nerve agent poisoned Sergei and Yulia Skripal.
The OPCW chemical weapons watchdog has supported Britain's analysis of a nerve agent used to poison a Russian former spy in the UK.
OPCW analysts, based in The Hague, took blood samples from the Skripals as they were treated in Salisbury Hospital after the March 4 poisoning.
Following the OPCW report published Thursday, the U.K. called for a United Nations Security Council meeting over the results, which will most likely be set for next week.
Johnson said the chemical "was a military grade nerve agent - a Novichok", a group of deadly chemical compounds reportedly developed by the Soviet government in the 1970s and 1980s.
The Organisation for the Prohibition of Chemical Weapons did not name the nerve agent as Novichok, but said it agreed with the UK's findings on its identity. "It is now up to Russian Federation to finally play a constructive role and answer the open questions", he said.
The OPCW laboratories tests' - the details of which were kept confidential - findings about the chemical's purity supports the British Government's assertion that a state was involved. The incident has led to a diplomatic crisis between Moscow and the West as Moscow denies any involvement and accuses Britain of inventing a "fake story".
He added, "The high purity of the substance will strengthen the UK's position that the agent was made by a highly proficient team and in a well refined process".
U.K. Foreign Secretary Boris Johnson quickly commented on the OPCW's report, saying that the results prove Britain's thesis on the matter.

Aaron Ramsey made it 6-3 with seconds left to cement a result that was long in doubt. Welbeck said the Gunners survived a "difficult" night.
"We would like to make sure that the statement really belongs to Yulia", the Russian Embassy in Britain said in a statement on Wednesday.
The government of Prime Minister Theresa May expelled 23 Russian diplomats in retaliation and called on ir global allies to follow in ir footsteps.
In a statement issued on her behalf by British police late on Wednesday, Skripal said her father remained seriously ill and she was still suffering from the effects of the military-grade Novichok nerve agent used against them.
At the same time, Russian Federation stepped up demands for diplomatic access to Skripal, who remains hospitalized, and his daughter, who is continuing her recovery in an undisclosed location after having been released from a hospital.
Meanwhile it is also hoped that Yulia's father Sergei will be discharged in due course after it was revealed that he was also recovering well.
She lives in Russian Federation but was visiting her father in Britain when they were poisoned.
She said she had declined an offer of assistance from the Russian embassy "at the moment".
A spokesperson from the Russian Embassy in London described Yulia Skripal's statement as "an interesting read". A new analysis from the worldwide oversight organization that enforces chemical weapons treaties doesn't directly name names, but the report falls foursquare behind the analysis of the UK's own investigators.
