Luke Harding is an award-winning foreign correspondent with the Guardian. Between 2007 and 2011 he was the Guardian's Moscow bureau chief; the Kremlin expelled him from the country in the first case of its kind since the cold war. He is the author of A Very Expensive Poison: The Definitive Story of the Murder of Litvinenko and Russia's War with the West, The Snowden Files: The Inside Story of the World's Most Wanted Man, and Mafia State, as well as the co-author of WikiLeaks: Inside Julian Assange's War on Secrecy and The Liar: The Fall of Jonathan Aitken (nominated for the Orwell Prize). Two of Harding's books have been made into films: The Fifth Estate and Snowden.
