Putin's proxy army was almost certainly guilty of killing the passengers on the Malaysia Airlines jet that came down in eastern Ukraine. He has questions to answer about the death of Alexander Litvinenko, pitilessly poisoned in a London restaurant.

His rivals find themselves locked up. Despite looking a bit like Dobby the House Elf, he is a ruthless and manipulative tyrant.
