UNITED NATIONS, April 19. /TASS/. The United Kingdom has crossed all red lines and ovetstepped thresholds of decency by accusing Russian President Vladimir Putin of being involved in the military chemical program, Russian Permanent Representative to the United Nations Vasily Nebenzya said on Wednesday at a United Nations Security Council meeting.

According to the Russian diplomat, the British side has circulated at the UN Security Council a letter "full of false, ungrounded and slanderous allegations, as usual." "The United Kingdom has dared to speak about our chemical statement in a preemptory manner, to judge the methods of work of our special services. This time, our British colleagues have gone even further: they directly accused President Putin of being involved in the chemical military program," he said.

"I don’t know whether London or the UK’s mission here see that you have overstepped the red line and the threshold of decency. I think you should say thanks to our president for his being a man of nerve," Nebenzya said, adding that these actions are nothing but an attempt to "demonize Russia and challenge its legitimacy and role on the global arena."

On March 4, former Russian military intelligence officer Sergei Skripal, 66, who had been earlier sentenced in Russia for spying for the UK, and his daughter Yulia, 33, were found unconscious on a bench near the Maltings shopping center in Salisbury, UK. Police said they had been exposed to a nerve agent.

Later, London claimed that the toxin of Novichok-class had been allegedly developed in Russia. With that, the UK rushed to accuse Russia of being involved, while failing to produce any evidence. Moscow refuted the accusations that it had participated in the incident and points out that neither the Soviet Union nor Russia have ever done research into that toxic chemical.
