Which voting system fits your preferences?
There's no single "best" electoral system — it depends on what you value. Answer a few quick questions below and we'll show you which systems match. Skip any question you don't have a strong opinion on.
Should every area keep its own single MP?
Should voters get a second vote for a party, alongside their local vote?
Is it OK if some MPs represent local areas and others represent parties or regions?
Right now you can only vote for one candidate. If you could express more of your opinion, how would you prefer to do it?
Is it OK to change the number of MPs in Parliament?
