"Strategic blow against the Russian Intelligence Services": UK says over 400 Russian spies expelled from Europe

This is reported by Reuters.

According to McCallum, more than 600 Russian officials were expelled from Europe, 400 of whom turned out to be spies. He noted that this is the biggest strategic blow against the Russian Intelligence Services in recent European history.

“This has struck the most significant strategic blow against the Russian Intelligence Services in recent European history. And together with coordinated waves of sanctions, the scale has taken Putin by surprise,” MI5 chief said. 

In addition, McCallum noted that Great Britain has refused more than a hundred applications for Russian diplomatic visas on national security grounds.
