Putin 'moves family members to Siberian 'underground city'

Vladimir Putin has in recent days hidden his family members in an 'underground city' in Siberia, according to a Russian professor.

The luxury hi-tech bunker is located in the Altai Mountains and was designed for protection in the event of nuclear war, said political scientist Valery Solovey, 61.

Formerly a professor at Moscow State Institute of International Relations (MGIMO) - attended by future top diplomats and spies, Solovey has previously alleged Putin suffers medical problems hidden from the Russian public, and has taken part in bizarre secret shamanic rituals alongside his defence minister Sergey Shoigu.
