Parliamentary democracy

Parliamentary democracy is a democratic system where voters choose representatives to sit in Parliament and rule them. There are many different voting systems that can be used in Parliamentary democracies. The "first past the post" system as in the United Kingdom frequently results in one party with a majority sufficiently so that one party can govern. By contrast "proportional representation" frequently leads to many relatively small parties where no one party is large enough to govern. Under proportional representation coalition governments are the norm in many countries.
