The Federal Assembly is the bicameral national legislature of Russia. The upper house is the Federation Council, and the lower house is the State Duma. The assembly was established by the Constitution of the Russian Federation in 1993, replacing the former Supreme Soviet of Russia. It is located in Moscow.
The Chairman of the Federation Council is the third most important position after the President and the Prime Minister. In the case that both the President and the Prime Minister are incapacitated, the Speaker of the upper house of the Russian parliament becomes Acting President of Russia.
