Russia has given a British diplomat one week to leave the country, days after the UK ordered Russia’s defence attache in London to leave, claiming he was a spy.

The orders for Captain Adrian Coghill, a Royal Naval officer based at the British Embassy in Moscow, to leave were revealed in a post on the Russian foreign ministry’s Telegram channel.

Defence Secretary Grant Shapps described it as a “desperate move”.

“Whilst Russia’s DA in the UK was acting as a spy, Putin’s only issue with ours was that they personified the UK’s unwavering support for Ukraine in the face of his illegal and barbaric invasion, he said.

The Kremlin’s move follows the expulsion on 8 May of Russia’s defence attache in London, Colonel Maxim Elovik, on the grounds that he was an “undeclared military intelligence officer”.

In its Telegram post, Russia’s foreign ministry said it had summoned an official from the British Embassy to protest over Col Elovik’s expulsion, which it described as “politically motivated” and “Russophobic”.

It added that this would not be the end of the matter, and “further retaliatory steps” would be announced.

As well as expelling Col Elovik, Home Secretary James Cleverly told the Commons last week he was revoking the diplomatic status of two Russian-owned properties in the UK that were believed to have been used for intelligence purposes, and placing new restrictions on Russian diplomatic visas.

Announcing the measures, Mr Cleverly predicted that they would be met with accusations of “Russophobia”, adding: “This is not new and the British people and the British Government will not fall for it, and will not be taken for fools by Putin’s bots, trolls and lackeys.”

The decision followed news that five men had been charged with offences under the National Security Act in connection with alleged espionage activities in the UK on behalf of Russia.
