Vladimir Putin has been sworn in for his fifth term as Russia's president in front of dignitaries, celebrities and friends, including US actor Steven Seagal and a biker gang leader known as 'The Surgeon'. -snip- Also in attendance was Chechen warlord Ramzan Kadyrov, a crony of Putin's who has been the subject of claims that he is terminally ill in recent weeks.
