A simulation of a nuclear attack appeared on a popular Russian show, in which a graphic showing how long it would take for a rocket fired from Kaliningrad in the Baltic Sea to reach major capitals in Europe.
According to the displayed graphic, it would take 106 seconds for a Russian nuclear warhead to reach Berlin, 200 seconds to Paris and 202 seconds to London!
Chairman of the nationalist Rodina party, Alexei Zuravlyov, said that Britain would no longer exist in such a situation.
"One Sarmat and that's it – the British Isles existed once, the British Isles don’t exist anymore. I'm serious," he said.
State Duma deputy Yevgeny Popov from the United Russia party argued that Britain also has nuclear weapons, and if a Sarmat missile is used, "no one will survive" in this war, "no one will be [left] on the planet."
"We’ll start over, from scratch," commented Skabeeva.
The move follows Russian television following reports that Vladimir Putin could use the May 9 Victory Day parade to declare a full-scale war on Ukraine.
In response to the western support of Ukraine, Putin ordered the military to test-fire its Sarmat missiles, which are also known as Satan II.
According to the Daily Mail, last week Putin bragged that his country's hypersonic missiles could "break through all modern defences" and could be ready to strike the UK "by autumn".
The remarks were made on one of Russia's most watched TV programmes, while hosts and guests discussed comments made by James Heappey, the UK Armed Forces Minister, in which he said strikes by Ukraine on Russian soil would be "legitimate" if they disrupted supply lines.
The show has been hosted by wife and husband Olga Skabeyeva and Evgeny Popov, who are married with each other, since September 2016, and is one of Russia's most watched programmes.
On the show a furious Zhuravlyov said: "One Sarmat [missile] and that's it - the British Isles are no more."
When Skabeyeva cautioned "but we are serious people", the politician hit back "and I am saying that seriously."
"They're accusing us of state terrorism", he fumed, prompting Popov to say "the UK also has nuclear weapons".
Popov added: "No one will survive in this war when you propose the strike with a Sarmat. Do you understand that no one will survive? No one on the planet."
Zhuravlyov doubled down, declaring "we'll start with a blank slate", before saying the missiles "can't be intercepted".
"Their abilities are limited. They say they can shoot it down, we'll see about that," he added.
A map showing the how quickly the missiles could hit the capital cities of the UK, France and Germany was then put on the screen by the producers, indicating the missiles could be launched from Kaliningrad.
Skabeyeva urged caution, saying: "Sarmats are not in Kalinigrad yet. From Kaliningrad to Berlin is 106 seconds, from Kaliningrad to Paris is 200 second. You're interested in London, 202 seconds to London."
An incandescent Zhuravlyov continued: "They need to be shown this picture. 'Guys look at this picture - count the seconds, can you make it? Hello, it's already here'."
As Popov struggles to contain his laughter, Zhuravlyov says: "That's the way. Let them think about it. Get a stopwatch, count (to) 220 seconds. That's how you talk to them, they don't understand anything else."
The tirade came after Mr Heappey told Times Radio it is "completely legitimate" for Ukraine to launch attacks on Russian soil.
He said: "It is completely legitimate for Ukraine to be targeting in Russia's depth in order to disrupt the logistics that if they weren't disrupted would directly contribute to death and carnage on Ukrainian soil.
"There are lots of countries around the world that operate kit that they have imported from other countries; when those bits of kit are used we tend not to blame the country that manufactured it, you blame the country that fired it."
