Ben is a member of the Plaid Cymru party.
This means Ben will vote in line with Plaid Cymru goals and principles.
In return the Plaid Cymru party has provided staff and funding support for Ben's campaign.
Ben may not always vote in line with Plaid Cymru goals and is in principle free to "rebel". However, rebelling regularly will likely result in removal from the party, and so the loss of benefits associated with being their representative - so it should be a rare event.
The Plaid Cymru Party Principles
A second referendum on EU membership
£20bn green jobs investment in Wales
Oppose new nuclear sites in Wales
Electrify Wales's main rail lines by 2030
Free social care at the point of need
There is no other party with higher ambition for Wales. There is no other party who always, without fail, puts Wales first. There is no other party who believes, above all else, that the solutions to Welsh problems are in our hands.
