A senior authorities supply instructed The Times: “From the very beginning of the invasion, one of the most obvious scenarios was that the war could lead to political unrest back home in Russia.

“We have to wait, watch and see what comes next. This could be chapter one of something new. Or it might be all over for Wagner. We must prepare for a whole range of different scenarios.”

Antony Blinken, the US secretary of state, mentioned the revolt confirmed "real cracks" in Mr Putin's regime.

He instructed CBS News: “This was a direct challenge to Putin’s authority. It raises profound questions.”

Conservative MPs have warned it spells the start of the tip for the Russian chief.

Tobias Ellwood, chairman of the Commons Defence Committee and a former soldier, instructed the Express: "It is game-changing and it is harmful. We've moved into a really risky interval for Russia.

"The quick might have been subtle however this can be a harmful game-changer for Putin and his days at the moment are, for my part, numbered.

“The Wagner group may have been muted and its leader exiled but Putin is significantly weakened and his enemies are now circling, realising that his whole pretence of power is diminishing.

“When a Russian leader has to contain a coup by offering the coup leader a place in exile rather than defeating him directly then you know power is draining from the Kremlin.”

So the troopers are going to know what is going on on.

"Secondly, I think Putin is finished, whether it's going to take two days or two years to finish him off. Once your dictator loses the appearance of invincibility, loses the appearance of strength, their days absolutely are numbered.

"And I feel thirdly, internally for Russia, I feel very severe machinations or plotting is now going to start."
