"Time has come for British authorities to apologize to Russia for the hollow accusations accompanied by an unprecedented anti-Russian campaign, to give answers to all the questions and requests officially sent to the British side on this matter, to engage with Russian law enforcement agencies that have opened the criminal case regarding the attempted murder of Yulia Skripal, and to stop isolating the two Russian citizens," the embassy’s press release read.
Meanwhile, Russian President Vladimir Putin urged to stop speculations on the so-called Skripal case and conduct a joint objective investigation instead.
"We need to either carry out a joint objective and thorough investigation, or simply stop talking on this topic, because it does not lead to anything but a deterioration of relations," he said.
Putin also questioned the alleged fact of poisoning of ex-spy Sergei Skripal and his daughter by a military-grade nerve agent.
"I'm not a specialist in chemical warfare agents, but as far as I can imagine, if a warfare agent is used, the victims of this attack die on the spot, almost immediately. But nothing happened in this case. Skripal himself and his daughter are alive, and have been discharged from the hospital. His daughter looks quite alright, everyone is alive and well," the president stressed.
On May 1, UK National Security Adviser Mark Sedwill told the UK lower house defense committee that no suspects had been identified in the March's attack on the former Russian intelligence officer Sergei Skripal and his daughter in Salisbury.
The United Kingdom and its allies have blamed Russia for an alleged role in the poisoning despite presenting no proof. Over a hundred Russian diplomats have since been expelled from these countries in solidarity with London and to put pressure on Moscow, which denies any involvement.
