A parliamentary system keeps the government in power only while the legislature backs it

the gist

In a parliamentary system the head of government, usually a prime minister, needs the confidence of a majority in parliament and can be removed if that support is lost. This differs from a presidential system, where the president is elected separately and cannot be replaced by a simple vote. The head of state may be a monarch or a ceremonial president, while the prime minister runs the government.

how it works

The prime minister is chosen from the parliament and stays in office only while a majority supports the government. If that majority is lost, the government can fall and a new one must be formed, often without a general election.

so what

Most of the European Union, Oceania and the former British Empire use this model, so it shapes how governments form and fall for much of the world's population.

has this happened before?

Many countries that adopted the Westminster model after British rule kept this structure, while others such as Germany and Italy use it with different methods for choosing a head of state. The same system lets parliaments end governments mid-term, which is why such changes can happen quickly.
