Tensions between the two nations are reaching boiling point as the Kremlin reacted this morning to the latest from London.
Theresa May has this afternoon imposed harsh retaliatory measures on Russia, including the expulsion of 23 high-level diplomats – the biggest such dismissal in 30 years.
Putin’s spokesman Dmitry Peskov this morning reiterated Moscow’s claim the Kremlin had “no connection” to the poisoning of double agent Sergei Skripal in Salisbury and issued a stark warning to the UK.
Russian news agency Tass quoted Mr Peskov as saying: “Moscow’s stance is well-known, London was told about Moscow’s position through diplomatic channels. Moscow has no connection to the incident that took place in the United Kingdom.
“Moscow won’t accept absolutely unfounded accusations against it, which are not substantiated by any evidence, and won’t accept the language of ultimatum.”
