Moscow (CNN)He's one of the most powerful men in the world. Born in St Petersburg in 1952, Vladimir Putin worked as a KGB spy in East Germany before going into politics -- working his way up from the mayor's office in St Petersburg to the top job of President.

Estimates of his personal wealth vary wildly -- officially he owns a small apartment, garage and a few cars, but at least one estimate puts his personal wealth at up to $200 billion.
According to Putin's spokesperson, Dmitry Peskov, suggestions of vast wealth are a "perverted commenting of reality."
