Amid the growing unrest in Russia, informed sources claim that opponents of President Vladimir Putin are poised to challenge his authority, according to

Dr. Yuri Felshtinsky, a distinguished Russian historian, has raised concerns over the aftermath of a potential upheaval in Putin's administration, predicting that the fallout could be "something catastrophic."

In an interview with Express, Felshtinsky stated, "Putin has established a regime that echoes the volatility and brutality of Hitler's and Stalin's eras. If circumstances lead to his replacement, it suggests that a catastrophic event has occurred."

The historian suggested that Russian Prime Minister Mikhail Mishustin and former President Dimitry Medvedev might be leading contenders to succeed Putin.

He told Express, "Medvedev, the ex-president, may fancy a shot at the presidency again. However, his influence largely originates from his close relationship with Putin. Should Putin be removed from power, Medvedev's political prominence could dwindle quickly due to their strong ties."

On the other hand, Felshtinsky believes Mishustin may serve more as an administrator, given his relatively low profile among the Russian populace.

"Mishustin is constitutionally expected to serve as the Acting President until fresh elections are held. But his limited popularity means he is unlikely to make any enduring mark on the country's politics," he explained.

The escalating tensions with Ukraine have substantially dented Putin's domestic political leverage. Ever since the onset of the conflict in February 2002, rumors of a rift between Putin and Yevgeny Prigozhin, the leader of the Wagner group, have been rife.

As reported by RadarOnline, some Kremlin insiders speculate that Prigozhin might emerge as Putin's successor, should a political shift occur.

With the enduring military deadlock with Ukraine and the tumultuous reign of Putin, Russia currently finds itself in a precarious situation. While Putin maintains his grip on power for now, increasing dissent and uncertainty loom over Russia's future.
