The politics of Turkmenistan take place in the framework of a presidential republic, with the President both head of state and head of government. Under Niyazov, Turkmenistan had a one-party system; however, in September 2008, the People's Council unanimously passed a resolution adopting a new Constitution. The latter resulted in the abolition of the council and a significant increase in the size of Parliament in December 2008 and also permits the formation of multiple political parties.
