The whistleblower told Vladimir Osechkin, who is on Russia’s most wanted list for exposing prison abuse, in a series of letters, nearly a dozen of which Mr Osechkin published. According to Mr. Osechkin, the risk intelligence agents are taking by speaking out is a sign of their growing rage at Putin. This comes as up to 40,000 Russian troops are thought to have been killed, injured, or captured since Russia’s invasion of Ukraine, dealing a major blow to Russian President Vladimir Putin.

The risk of a coup against President Putin by the Federal Security Service (FSB) grows with each week that the war in Ukraine continues, according to a whistleblower at the heart of Russian intelligence.

In letters, the whistleblower told Vladimir Osechkin, who is on Russia’s most-wanted list for his work exposing prison abuse, that chaos and discontent have engulfed the security services following the botched invasion of Ukraine.

According to a source within Russia’s security service, the FSB, agents are growing increasingly dissatisfied with Putin’s handling of the war.

According to Russian journalist Vladimir Osechkin, who cited his source, Western sanctions are crippling the lifestyle of his country’s high-flying secret service agents, who are allegedly barred from visiting their vacation homes or taking their children to Disneyland Paris.

According to The Sun UK, FSB officers are paid more than the average Russian and are provided with an apartment.

Osechin told The New York Times: “Putin has been responsible for Russia’s stability for the past 20 years. Officers of the FSB, police officers, and state prosecutors — those inside the system — were able to live normal lives.”

He claimed that Western sanctions were ruining the situation and adding to the Russian leader’s collective disillusionment.

“For every week and month that this war continues, the possibility of a rebellion by those in the security services grows,” Osechkin said.
