Seeking re-election this weekend, Russian President Vladimir Putin has been accused by Britain of ordering the nerve agent attack on a ex-Russian spy on United Kingdom soil.
While Britain has accused the Russian state of ordering the poisoning of the Skripals, Foreign Secretary Boris Johnson took it a step further Friday and said it's "overwhelmingly likely" that Putin himself ordered the attack.
"That's why a new concept of state security emerged a year ago, in which Russian Federation was called a serious enemy of Great Britain", Yakovenko said.
The statement came after the Foreign Ministry on Thursday condemned "the event that occurred in Great Britain" but made no mention of Russian Federation.
Peskov also said that Russian Federation is "perplexed and does not comprehend the British leadership's stance" and insisted the "accusations are unsubstantiated".
There has been a huge outcry against the Russians and this has obviously been replicated in Parliament with the prime minister and the leader of the opposition trading blows on who is culpable for the attack.
The implication of the ambassador's comments is that the Russians have been told by the British the exact nerve agent deployed.More news: Rabada appeal hearing set for March 19
