"Yesterday the Kremlin said it would close the British Council and our Consulate in St Petersburg. These futile measures will only punish ordinary Russians by depriving them of harmless opportunities to learn English and apply for UK visas," Johnson said in his op-ed article for The Sun newspaper published on Sunday.
He also said that France, Germany and the United States supported London's version of Salisbury attack, while "Russia stands alone and isolated."
On Wednesday, May went on to announce a package of anti-Russian measures, including the expulsion of Russian diplomats from the country and the suspension of bilateral contacts between London and Moscow.
On Saturday, Russia announced retaliatory measures against the United Kingdom, declaring 23 employees of the UK Embassy in Moscow personae non grata in response to London's move.
Moscow also revoked its agreement on opening and operation of the UK Consulate General in the Russian city of St. Petersburg, according to the statement. In addition, a decision was made to terminate the activities of the British Council in Russia, since its "legal status has not been determined."
