How do parties actually vote?

Compare any two parties on a specific issue to see an AI-generated narrative breakdown, or browse the full voting heatmap below.

How to read the heatmap

Each cell shows what percentage of a party's votes were “aye” (in favour) on that issue. Darker green = voted aye more often. Darker red = voted no more often. Grey = no data.

Important context

In Parliament, the governing party (currently Labour) typically votes “aye” on its own legislation, while opposition parties vote “no” — even on topics they may broadly support. These figures show voting direction, not policy alignment.

Notes on specific parties

Sinn Féin MPs do not take their seats at Westminster as a matter of policy (abstentionism). A 0% score does not mean they oppose these issues. Parties with very few MPs may show extreme percentages based on a small number of votes.

Data based on votes by current MPs only. Percentages show proportion of “aye” votes across all categorised divisions per policy area. Government parties tend to vote aye more often on their own legislation; opposition parties tend to vote no. See the explainer above for context.
