Semi-parliamentary system

Semi-parliamentary system can refer to one of the following:

  • a prime-ministerial system, in which voters simultaneously vote for both members of legislature and the prime minister
  • a system of government in which the legislature is split into two parts that are both directly elected – one that has the power to select and remove the members of the executive by a vote of no confidence and another that does not.

The former was first proposed by Maurice Duverger, who used it to refer to Israel from 1996 to 2001. The second was identified by German academic Steffen Ganghof.

Like semi-presidential systems, semi-parliamentary systems are a strongly rationalized form of parliamentary systems. After Israel decided to abolish the direct election of prime ministers in 2001, there are no national prime-ministerial systems in the world; however, a prime-ministerial system is used in Israeli and Italian cities and towns to elect mayors and councils.
