Vladimir Putin, after eight years as president of Russia and four more as prime minister, is stubbornly holding onto power. He has announced his intention to return as president and declared his party the winner in parliamentary elections that are widely seen as fraudulent. In Moscow 100,000 protesters have taken to the streets in the largest demonstrations since Putin took office. Putin began his career as a KGB spy but when he became president, he made himself a valued ally of the West. How did he do it? And what made Washington and London turn against him? This four-part series is made by Norma Percy and the team at Brook Lapping with a track record for getting behind closed doors with multi-award-winning series like The Death of Yugoslavia, The Second Russian Revolution, and Iran and the West. For the first time Putin's top colleagues - and the Western statesmen who eventually clashed with him - tell the inside story of one of the world's most powerful men.
