The UK will expel 23 Russian diplomats after Moscow refused to explain how a Russian-made nerve agent was used on a former spy in Salisbury, the PM says.
Theresa May said the diplomats, who have a week to leave, were identified as “undeclared intelligence officers”.
She also revoked an invitation to Russia’s foreign minister, and said the Royal Family would not attend the Fifa World Cup later this year.
Russia denies being involved in the attempted murder of Sergei Skripal.
It refused to meet Mrs May’s midnight deadline to co-operate in the case, prompting Mrs May to announce a series of measures intended to send a “clear message” to Russia.
Among them are plans to:
– Expel 23 diplomats – who have one week to leave
– Increase checks on private flights, customs and freight
– Freeze Russian state assets where there is evidence they may be used to threaten the life or property of UK nationals or residents
– Ministers and Royal Family to boycott the Fifa World Cup in Russia later this year
– Suspend all planned high level bi-lateral contacts between the UK and Russia
Mrs May told MPs that Russia had provided “no explanation” as to how the nerve agent came to be used in the UK, describing Moscow’s response as one of “sarcasm, contempt and defiance”.
The PM, who was earlier briefed by senior intelligence chiefs in Downing Street, added there was “no alternative conclusion other than that the Russian state was culpable” for the attempted murder of Mr Skripal and his daughter.
The pair remain critically ill in hospital after being found slumped on a park bench in the center of Salisbury on 4 March.
Det Sgt Nick Bailey also fell ill responding to the incident, and is in a serious but stable condition, but is thought to be improving.
