Prime Minister's Questions explained: what it is, why it's so famous, and whether it really holds the Prime Minister to account
Prime Minister’s Questions (PMQs) is a weekly 30-minute House of Commons session where MPs question the Prime Minister on government policy and decisions. While often criticised for political point-scoring, confrontation and a lack of direct answers, PMQs remains an important tool for holding the government publicly accountable. The article explores how PMQs works, its effectiveness in scrutinising government, potential reforms and its wider constitutional importance in British democracy.

What you need to know:
- PMQs takes place every Wednesday when Parliament is sitting.
- MPs can question the Prime Minister on any aspect of government policy.
- The Leader of the Opposition is allocated six questions each week and the leader of the third largest party is allocated two questions.
- Critics argue that political theatre and point-scoring can sometimes limit effective scrutiny.
Every Wednesday lunchtime (12pm) attention turns to the House of Commons for Prime Minister's Questions (PMQs). It is one of the most recognisable features of British politics and often generates headlines that shape the rest of the political week.
But PMQs is more than political theatre. It is Parliament's most visible opportunity to hold the Prime Minister publicly accountable for the actions of their government.
What is Prime Minister's Questions?
Prime Minister's Questions is a weekly Commons session where MPs question the Prime Minister about government policy and current political issues.
Unlike departmental question times, which focus on a particular department, MPs can ask about almost any matter for which the government is responsible. This reflects the constitutional principle that the Prime Minister, as head of government, is accountable for the actions of the government as a whole.
The session lasts for 30 minutes and takes place every Wednesday at noon. While this format feels well established, it only dates from 1997, when two 15-minute sessions were merged into a single weekly event.
How does PMQs work?
MPs enter a ballot to be selected to ask questions. Unlike departmental question times, MPs do not submit their question in advance. This means the Prime Minister has no warning about what will be asked.
The session is dominated by exchanges between the Prime Minister and the Leader of the Opposition, who is entitled to ask six questions. The leader of the third-largest party receives two questions.
For many viewers, these clashes are the defining feature of PMQs and are often treated as a weekly test of political leadership.
So, does PMQs actually work?
That depends on how success is defined.
If success means forcing immediate policy change or securing direct answers, PMQs often falls short. Time is limited, exchanges can become highly partisan, and Prime Ministers frequently avoid answering questions directly.
Research by the Hansard Society found that many members of the public view PMQs as excessively confrontational, describing it as "childish", "noisy", "over the top" and "pointless". Two-thirds of participants believed there was too much political point-scoring and not enough answering of questions.
Research has also found that interruptions and personal attacks have increased over time, while exchanges between the Prime Minister and Leader of the Opposition take up an increasing share of the available time, leaving fewer opportunities for backbench MPs.
Yet judging PMQs solely on the answers given in the chamber risks missing its wider purpose. The Prime Minister and their team know they will face public scrutiny every week, forcing them to prepare for difficult questions and defend government decisions. Issues raised at PMQs can shape media coverage and increase political pressure on governments.
Could PMQs be reformed?
Several reforms have been proposed. Some commentators argue that requiring questions to be submitted in advance could encourage fuller answers. Others suggest extending the session so more MPs can participate and raise constituency concerns.
Another option would be to separate leader-to-leader exchanges from backbench scrutiny, something already seen in the Scottish Parliament.
However, it seems unlikely that PMQs will ever lose its theatrical character. The challenge is improving scrutiny without losing the public attention that makes the session so influential.
Looking beyond the theatre
The cheering, jeering and political point-scoring often dominate public perceptions of PMQs. Yet focusing only on the spectacle risks overlooking its constitutional importance.
At its heart, PMQs exists because Parliament expects the Prime Minister to explain and defend the actions of government in public. While it may not always produce direct answers or immediate policy change, it remains one of the most visible ways in which elected representatives can challenge political power.
