A question time in a parliament occurs when members of the parliament ask questions of government ministers (including the prime minister), which they are obliged to answer. It usually occurs daily while parliament is sitting, though it can be cancelled in exceptional circumstances. Question time originated in the Westminster system of the United Kingdom, and occurs in other countries, mostly Commonwealth countries, who use the system.

In practice, the questions asked in question time are often pre-arranged by the organisers of each party, although the questions are usually without notice. Questions from government backbenchers are either intended to allow the Minister to discuss the virtues of government policy, or to attack the opposition.
