Vladimir Putin could be toppled by a secret plot by his own inner circle, a CIA insider has claimed.
Hoffman said any such attempt to overthrow the president would be sudden, swift and potentially deadly.
“These guys that are going to do it are going to be so secret about it so that Putin doesn’t find them and kill them first,” said Mr Hoffman. “It’ll happen all of a sudden. And he’ll be dead.
“Nobody’s gonna ask, ‘Hey Vladimir, would you like to leave?’ No. It’s a f****** hammer to the head and he’s dead,” he told The Daily Beast. “Or it’s time to go to the sanatorium. They schwack him for it. That’s what they’ll do.”
There is also ongoing speculation about Putin’s health, which has also raised questions over his future leadership of the country.
According to Mr Hoffman, there are three key figures to keep a watchful eye on should the Russian president be replaced.
They are; defence minister Sergei Shoigu, who has played a crucial role during Russia’s war in Ukraine; Nikolai Patrushev, the chief of Putin’s Security Council and Alexander Bortnikoc, the director of Russia’s secretive intelligence agency FSB.
Another former CIA officer Ronald Marks also said that Russia could be on its way to getting a new leader, which would prompt “a mad-dash scramble” for power.
It comes as Putin’s war on Ukraine entered its fifth month and while it was widely considered a botched operation at the start, more recently Russia has been making gains in the east.
Russian forces are seeking to seize the last remaining Ukrainian strongholds in the eastern Luhansk region after taking full control of the charred ruins of Sievierodonetsk on Saturday.
On Sunday, Putin launched the first airstrikes against Kyiv in three weeks just as world leaders met at the G7 summit in Germany.
Attending the event, Boris Johnson urged western allies to stand firm over Ukraine.
“The consequences of what’s happening for the world are tough, he said. “But the price of backing down, the price of allowing Putin to succeed, to hack off huge parts of Ukraine, to continue with his programme of conquest, that price will be far, far higher and everybody here understands that.”
