Debates in Parliament

A debate is a formal discussion of a proposal (a motion) before it is decided on. 

Parliament holds debates on behalf of the nation and its decisions can be of great public interest or national importance. Debates can also be used to explore a topic in depth or bring to light a particular concern, without requiring any significant decision. 

In the Commons, MPs will often cite the experience of their constituents or bring an important regional perspective to the topic. In the House of Lords, debates benefit from the contributions of members with expertise and professional experience in almost every field.

The speeches made during parliamentary debates are captured in Hansard, so that a public record is maintained of Parliament’s deliberations. This is an essential resource for historians and others seeking to understand the context in which important decisions were made.

Debates on substantive motions 

When a motion for debate asks the House to take some action or express its opinion on something it is described as a substantive motion in the House of Commons. In the Lords it is described as a resolution. 

Before members are asked to vote on a motion, it is debated. This allows the House to hear the arguments in favour of the proposal and weigh them against those made by its opponents. It is also a chance for individual members to raise any specific concerns or insights they have and to hear differing perspectives on the proposal from across the House.  

In this way, debates are designed to help MPs and members of the House of Lords reach an informed decision. 

Debates on substantive motions must end with a clear result – in favour or against – and this may require a division of the House, where the votes of individual members are counted and recorded.

Debates on general (neutral) motions 

General debates take place on neutral motions that allow either House to debate a matter without finally expressing its opinion. An example of a neutral motion is ‘That the House has considered’ a topic.  

In the House of Lords these are known as ‘take note’ motions and are often worded ‘That this House takes note of’ a subject. 

General debates take place regularly in both Houses and on an enormous variety of topics. They might mark a historically significant anniversary or allow the House to focus on the situation in a particular country, region or sector of the economy, while others are prompted by a current campaign or petition.  

General debates can allow members to share their own knowledge or expertise in a subject and to hear accounts of others’ lived experience. This can help to broaden the understanding of a topic among members in each House and may influence opinion in the government or in the country at large. 

Backbenchers' short debates

Throughout the week, individual members introduce their own topics for a short debate on a neutral motion. These can provide a valuable exchange with a government minister on the member’s chosen issue and help to keep the government in touch with the individual concerns of members in both Houses. 

The format of debates 

For a debate to take place in either House, a motion must first be put to members: this takes the form of a proposal with which the House can either agree or disagree.

Debates in both Houses follow a similar format, with government and opposition frontbenchers speaking from the despatch boxes and other members standing up (if they are able) to speak in their places. But the distinct rules and conventions that operate in each House mean that there are important differences between the way debates are conducted in the House of Commons and in the House of Lords.
