UK Foreign Secretary Boris Johnson said Friday it was "overwhelmingly likely" that Russian President Vladimir Putin personally gave the order to use a nerve agent to attack a former double spy in what's the most direct accusation yet against Russia's leader.
Putin spokesman Dmitry Peskov was quoted by Russian news agencies as calling Johnson's statement a "shocking and inexcusable breach of diplomatic propriety".
Dmitry Peskov, Putin's spokesman, responded to Bloomberg over text message: "We have said on different levels and occasions that Russian Federation has nothing to do with this story".
The escalating worldwide scandal is unfolding as Skripal and his daughter remain in critical condition after exposure to the Soviet-designed chemical Novichok on March 4 in the English city of Salisbury. British police said they were treating Glushkov's death as unexplained, but did not think it was linked to the attack on the Skripals.
"We have never encountered this level of discussion on the global stage", Peskov told reporters.
Britain has accused Russian Federation of staging the attack with the Soviet-designed Novichok nerve agent, accusations Moscow has denied. He said Russia's recent provocations need a tough response, including action against Russian oligarchs with questionable ties who have used London as a safe haven.
Russian Federation has repeatedly dismissed the UK's accusations as "unfounded" and warned it would retaliate over the expulsion of its diplomats. Moscow has fiercely denied its involvement and warned it would respond.
The prime minister demanded that Russian Federation give the British government an official response by Tuesday at midnight. "There is to be no Russophobia as a result of what is happening", he said.
Former military intelligence agent Sergei Skripal had been pardoned and was "no longer a threat to Russia", Nebenzia argued, but at the same time, he could clearly serve as "the flawless victim who could justify any unthinkable lie, any kind of untruth tarnishing Russia".
A United Kingdom inquiry found that two Russian agents poisoned Litvinenko at a London hotel bar in 2006 by spiking his tea with highly radioactive polonium-210, and that Putin "probably approved" Litvinenko's killing.
Labour Party leader Jeremy Corbyn says in a newspaper column that politicians must not "rush way ahead of the evidence being gathered by the police". Corbyn said in the Guardian that it's possible that "Russian mafia-like groups", rather than the Russian state, were responsible.
The attack marks the first known use of the substance that was developed by the Soviet military since World War II and has marked a new low in relations between Britain and Russian Federation in the post-Cold War era.
May told Turnbull that she visited Salisbury on Thursday and that the act "represented an unlawful use of force by the Russian state against the U.K". He was granted refuge in the UK after a high-profile spy exchange between the United States and Russian Federation in 2010.
