HOME SECRETARY Yvette Cooper denounced “aggressive language” from Vladimir Putin today after the Russian leader threatened to strike Britain in revenge for British-made missiles being fired on Russia.

Mr Putin said Russia has tested a new intermediate-range weapon in an attack on Dnipro in response to Britain and the US allowing Ukraine to fire long-range missiles they supply at targets on Russian soil.

The US said the weapon was a new, experimental intermediate-range missile based on Russia’s existing RS-26 Rubezh intercontinental ballistic missile, which could potentially hit Britain.

Asked about the Russian leader’s threat to use weapons against nations that allow their own weapons to be used against Russia, she told Sky News: “Russia invaded a sovereign state.

“We have seen the aggressive, blustering tone and response from Putin all the way through this, it’s completely unacceptable, and we will continue to see that sort of aggressive language.

“We are clear that sort of behaviour cannot be tolerated, and that’s why we have provided the support to Ukraine as they defend themselves against Putin’s aggression.”

Foreign Secretary David Lammy has meanwhile vowed to continue to “do everything that is necessary” to help Ukraine combat Russia.

But CND general secretary Sophie Bolt said: “There has to be a de-escalation. We’re just seeing escalation, upon escalation, upon escalation.

“There is a real threat now that Nato is going to be drawn into an all-out confrontation with Russia, so that’s two nuclear-armed powers, and the Ukrainian people are in the middle of this.

“We know that polls show the Ukrainian people want this war to end.

“They have had enough, they want it to end quickly through peace talks.”
