A parliament in all but name, Russia's Duma is essentially a rubber-stamp body for the Kremlin, and the chamber's 450 deputies are very generously rewarded.

The official salary is $78,610 (£60.5k) a year, over 10 times higher than Russia's average annual wage. And that's not even taking into account reports of their hidden wealth, with Russia the second most corrupt country in this round-up.
