80 to 100 member Senedd backed as part of Plaid-Labour cooperation agreement

An 80 to 100 member Senedd has been backed by the Plaid Cymru and Labour cooperation agreement in the Senedd.

The agreement includes a commitment to supporting plans for an expanded Welsh Parliament – up at least 20 from the current 60 – that would require a two-thirds majority to get through.

It also includes a commitment to either retain the current proportional representation system or bring about reforms to make the voting system more proportional still.

Last year, a report by Labour and Plaid members on a Senedd committee backed expanding to 90 members, from the current 60.

The agreement text states that Plaid Cymru and Labour will “support plans to reform the Senedd, based on 80 to 100 Members; a voting system, which is as proportional – or more – than the current one and have gender quotas in law.

“We will support the work of the Senedd Special Purpose Committee and introduce a Senedd reform Bill 12 to 18 months after it reports.”

The agreement between Plaid Cymru and Labour is a joint policy programme covering 46 areas, ranging from the delivery of free school meals to all primary school pupils; a commitment to take immediate and radical action to address the second homes crisis, to long-term reform of the Senedd.

Plaid Cymru Members will not be joining the Welsh Government as Ministers or Deputy Ministers. Plaid Cymru will instead appoint a designated lead member for the agreement and committees made up of Welsh Ministers and Plaid Cymru designated members will be established to reach agreement on issues covered by the Co-operation Agreement.


Both Plaid Cymru and the Liberal Democrats have previously backed having a bigger Senedd, providing the required 40 seat majority to make changes, but the Conservatives oppose the move.

A sticking point however could be how proportional the new system would be. The current semi-proportional system, where 2/3 of members are voted in through First Past the Post in constituencies, favours the Labour Party.

In 2017, Cardiff University’s Professor Laura McAllister conducted an in-depth review on the issue. Her Expert Panel on Assembly Electoral Reform recommended the Assembly should be increased to between 80 and 90 members and also a change to a Single Transferable Vote system of choosing MS.

Mark Drakeford said in May that there were still “significant practical issues to work through”

“I want to see the Senedd properly fit to discharge its responsibilities,” he said. “It’s a matter not just of numbers but it’s a matter of method of election as well, which is a thorny issue, on which there are many views”

However, he added that there was “growing enthusiasm” for a Welsh Parliament “fit to discharge its responsibilities”.

Pairing off the new westminster constituencies would give 16 swperetholaethau. Electing 5 MSs each would give a total of 80 MSs. Alternatively electing 6 MSs per swperetholaeth would give 96 MSs in total. Personally I would prefer a STV system to fill the seats but a d’Hondt-based system would also be feasible.

Personally I’d prefer no linkage with the current Westminster constituencies but use either the unitary authorities or pairing the current constituencies

I agree, pairing off the new constituencies to create 16 swperetholaethau – as you put it – and electing 5 (or possibly 6) MSs in each constituency is the best option available. The MSs should be selected on a PR basis within each of those 16 constituencies.

Quality governance must be the one and only aim. Those in elected positions and who are uncomfortable with this need to offer explanation.

The current numbership level does not allow for members from all parties to get their non Cardiff Bay work in local communities high enough.

With the reduction of MP numbers continuing and the loss of MEPs plus the changes within local councillors membership – a natural re balancing is needed.
