Vladimir Putin is at risk of a coup by the Federal Security Service (FSB) a whistleblower at the heart of Russian intelligence has said.
The whistleblow told Vladimir Osechkin, who is on Russia’s most-wanted list for exposing abuse in prisons, in a series of letters – almost a dozen of which, Mr Osechkin has published.
Mr Osechkin told The Times that the risk intelligence agents are taking by speaking out is a sign of their growing anger towards Putin.
This comes as up to 40,000 Russian troops are thought to have been killed, injured or captured since the invasion of Ukraine, in a major blow to the Russian leader.
