Foreign Secretary Boris Johnson has reassured Russians that the UK's dispute is specifically with "Putin's Kremlin", claiming it is "overwhelming likely it was his decision to direct the use of a nerve agent" in Britain. But Peskov repeated that "Russia has nothing to do with this story", in comments carried by Russian news agencies.
"Our quarrel is with Putin's Kremlin, and with his decision - and we think it overwhelmingly likely that it was his decision - to direct the use of a nerve agent on the streets of the United Kingdom".
Boris Johnson, while visiting the Battle of Britain Bunker museum in Uxbridge with his Polish counterpart, told reporters the British government has "nothing against" the Russian people and that their problem is with the Kremlin.
As the global scandal gathers pace, Skripal and his daughter remain in critical condition after exposure to the Soviet-designed chemical Novichok on March 4 in the southwestern English city of Salisbury.
The UK government says they were poisoned with a nerve agent of a type developed by Russian Federation called Novichok and PM Theresa May said she believed Moscow was "culpable".

At the same time, the British foreign secretary added that "we have nothing against the Russians themselves".
Mentioning Putin in the context of Sergei Skripal's poisoning "is nothing but shocking and unforgiveable behaviour from the point of view of diplomacy", Peskov said. "They're going to have to decide whether or not they want to be a good actor or a bad actor". Russian Federation has repeatedly denied any involvement in the attack.
Russian Federation denies being the source of the nerve agent used and has demanded Britain share samples collected by investigators.
Leaders from the United States, Germany and France joined the U.K.in accusing Russian Federation of being behind the attack in a statement Thursday.
But in an unexpected twist, Russian investigators said on Friday they had opened a criminal investigation into the attempted murder of Yulia Skripal and stood ready to co-operate with British authorities.
Lavrov also lashed out at Britain for not providing consular access to Yulia Skripal, who along with her father is in critical condition at a Salisbury hospital. He wished the Skripals a speedy recovery and said he hopes they can shed light on what happened when they are well. "It threatens the security of us all", the statement said.
