Parliamentary activity is often judged by visibility, but visibility alone can be misleading. Parties with large parliamentary groups naturally dominate debate time, while smaller parties can appear quieter despite high individual engagement.
To understand the activity properly, it helps to look at the data from multiple angles.
Below is a breakdown of House of Commons contributions in 2025, viewed both per MP and in total volume.
Relative contribution ranking (contributions per MP)
- Democratic Unionist Party – 387 per MP
- Traditional Unionist Voice – 257 per MP
- Green Party – 217 per MP
- Ulster Unionist Party – 200 per MP
- Conservative – 196 per MP
- Reform UK – 175 per MP
- Liberal Democrat – 154 per MP
- Scottish National Party – 154 per MP
- Labour – 149 per MP
- Plaid Cymru – 112 per MP
What this shows
Smaller parties are often more visible on a per-member basis.
With fewer MPs, participation is less dispersed, and individual members tend to contribute more frequently. This can reflect strategic use of parliamentary time, issue specialisation, or a greater reliance on oral contributions to exert influence.
Total contribution ranking
- Labour – 60,158
- Conservative – 22,690
- Liberal Democrat – 11,109
- Democratic Unionist Party – 1,934
- Independent – 1,406
- Reform UK – 1,396
- Scottish National Party – 1,383
- Green Party – 866
- Plaid Cymru – 447
- Traditional Unionist Voice – 257
What this shows
Total contributions broadly reflect parliamentary size and institutional role.
Larger parties dominate proceedings by volume, while smaller parties and independents — despite high individual activity — contribute far fewer interventions in aggregate.
A necessary caveat: These figures capture spoken and written contributions in the Commons chamber only. They do not account for select committee work, constituency activity, informal negotiations, or other forms of parliamentary influence that are central to legislative impact. Labour and Labour (Co-op) have been combined, and the Speaker has been removed.
