Changes

Many parliaments are made up of two different houses - for example the House of Representatives and the Senate in Australia.  The voting systems of the two houses are usually different meaning the mix of MPs from the various parties will also generally differ.

Usually in a parliamentary system, the government is formed by MPs from the party which has the majority of members.  The leader of that party is the head of government, often called the Prime Minister.  As the government party has a majority of members, it can usually expect to win any votes in the parliament.  In the situation where no one party has a majority, the largest party forms the government and must rely on the support from members of other parties to win votes. This is known as minority government.  The largest party in this situation might enter into a formal arrangement to receive support from another party in return for giving the "coalition" party a say in government affairs.

A minority goverment with members of one party only, which must rely on the support from members of other parties to win votes. The other possibility is a formal arrangement between two or more parties to form a coalition government with a majority of votes, where the government members are from all coalition partners.

This contrasts to presidential systems, where the members of the government (in particular the President) are not members of the legislature.

The Prime Minister is not elected for a fixed term, but serves for as long as he has the "confidence" of Parliament -- that is, as long as he enjoys their support.  Usually, the Prime Minister (and the rest of the government) is removed after an election at which his party failed to retain a majority in parliament.  Occasionally, most often during a period of minority government, the Prime Minister is removed upon losing a vote of no confidence, or resigns after losing a major vote on an issue they have championed (as [[Italy|Italian]] Prime Minister [[Romano Prodi]] did in February 2007).

First past the post elections are more likely to produce a parliament with two major parties, making minority government unlikely.  Proportional voting systems allow third parties a chance to win some representation if they can win a small amount of the national vote without winning a majority of any districts. They are more likely to result in minority government and frequent changes of government.

They are more likely to result in a minority or coalition government. In order to make it easier to form a majority government, proportional voting systems often favor large parties for example through thresholds or the way the number of seats are calculated from the votes.
