New voting system
The new voting system is called a ‘closed proportional list system’. This means you vote for a political party (rather than individuals) or an independent candidate.
The ballot paper will show the full list of candidates in your constituency, so you can still see who you're voting for.
If a party wins enough votes, they will win one or more seats in the Senedd. If an independent candidate wins enough votes, they will win a seat in the Senedd.
Seats will reflect the percentage of votes each party or independent candidate gets.
