The (UK)Home Office has expelled a Russian defence attache as part of a series of measures against Moscow.
James Cleverly said the measures come because of the "reckless and dangerous activities of the Russian government across Europe".
"I can tell the House [of Commons] that we will expel the Russian defence attache who is an undeclared military intelligence officer," he said.
He then outlined other measures in the package.
"We will remove diplomatic premises status from several Russian owned properties in the UK, including Seacocks House, a Russian owned-property in Sussex and the trade and defence section in Highgate, which we believe have been used for intelligence purposes.
"And we are imposing new restrictions on Russian diplomatic visas, including capping the length of time Russian diplomats can spend in the UK."
Mr Cleverly ended with a strongly worded statement.
"Our message to Russia is clear: Stop this illegal war. Withdraw your troops from Ukraine. Cease this malign activity."
