Russia constitution chapter 4 article 81 : 3. âOne person may not hold the position of Russian president for more than two terms in a row.â.

Russia's legislative branch is its Federal Assembly, which consists of a 178-seat Federation Council and 450-seat State Duma representing the 21 Russian Republics and 66 independent regions and territories.
