[1][2][3][4] Maurice Duverger's original definition of semi-presidentialism stated that the president had to be elected, possess significant power, and serve for a fixed term.
[7] Modern definitions merely declare that the head of state has to be elected and that a separate prime minister that is dependent on parliamentary confidence has to lead the legislative.
The president may choose the prime minister and cabinet, but only the parliament may approve them and remove them from office with a vote of no confidence.
This subtype is used in: Burkina Faso, Cape Verde,[8] East Timor,[8][9] France, Lithuania, Madagascar, Mali, Mongolia, Niger, Georgia (2013–2018), Poland (de facto, however, according to the Constitution, Poland is a parliamentary republic),[10][11][12] Portugal, Romania, São Tomé and Príncipe,[8] Sri Lanka, Turkey (de facto between 2014 and 2018, until the constitutional amendment to switch the government to presidential from parliamentary), and Ukraine (since 2014; previously, between 2006 and 2010).
Cohabitation can create either an effective system of checks and balances, or a period of bitter and tense stonewalling, depending on the attitudes of the two leaders, the ideologies of themselves/their parties, and the demands of their supporters.
This has significantly lowered the chances of cohabitation occurring, as parliamentary and presidential elections may now be conducted within a shorter span of each other.
[21][22] Advantages Disadvantages In a president-parliamentary system, the prime minister and cabinet are dually accountable to the president and the legislature.
