6/ The new system proportional system is more representative but makes a single-party majority in the Senedd less likely. With Plaid Cymru and Reform UK neck-and-neck in the polls, and Plaid ruling out any deal with Reform, forming a government next May could be anything but straightforward.

2/ So, what are the key changes?

Wales is moving from the additional member system to a closed list proportional representation system

The size of the Senedd increases from 60 to 96 MSs

The number of constituencies decreases from 40 to 16, with each constituency electing 6 MSs

No by-elections
