23 British diplomats have been expelled from Moscow by the Russian government over the nerve agent attack on an-ex spy and his daughter in the UK.
The Russian Foreign Ministry made it clear the British Council in Russia will be closed, which promotes cultural ties between the nations, and the British Consulate in St Petersburg.
UK Prime Minister Theresa May said: “We anticipated a response of this kind.”
She said that the government will consider its next steps “in the coming days, alongside our allies and partners”.
“We will never tolerate a threat to the life of British citizens and others on British soil from the Russian Government,” she added.
The UK ordered Russian diplomats to leave the country over the incident on 4 March which the UK government has blamed on Russia – but which Russia denies.
