The campaign was supported by both parties of the One Wales coalition government in the Assembly: Wales Labour Party and Plaid Cymru, as well as the Liberal Democrats. Although the Welsh Conservative Party were officially neutral all the Conservative AMs in the Assembly supported a Yes vote and the party group was represented on the Yes for Wales Steering Committee. The campaign also had the support of the other Permitted Participants recognised by the Electoral Commission: Cymru Yfory, Wales TUC and Unison.
