Which UK political reform would you most want to see happen in your lifetime?

Replacing the current voting system with one where seats more closely match the share of votes cast. Supporters say it ends safe seats; critics warn of permanent coalitions.

Turning the second chamber into a fully or mostly elected body, ending political appointments and hereditary peerages. A reform promised by parties for generations.

Codifying Britain's famously uncodified constitution into a single document, setting out rights, powers and limits in black and white.

Extending the right to vote in general elections to 16 and 17-year-olds, as already happens in Scottish and Welsh devolved elections.

Creating a devolved parliament for England to match Holyrood, the Senedd and Stormont, rather than relying on Westminster to wear two hats.
