Luke Daniel Harding (born 1968) is a British journalist working as a foreign correspondent for The Guardian. He was the correspondent of The Guardian in Russia from 2007 until, returning from a stay in the UK on 5 February 2011, he was refused re-entry to Russia and deported back the same day. The Guardian said his expulsion was linked with his critical articles on Russia, a claim denied by the Russian government. After the reversal of the decision on 9 February and the granting of a short-term visa, Harding chose not to seek a further visa extension. His 2011 book Mafia State discusses his experience in Russia and the political system under Vladimir Putin, which he describes as a mafia state.
