In the "One Wales" coalition agreement on 27 June 2007 the Wales Labour Party and Plaid Cymru made the commitment "to proceed to a successful outcome of a referendum for full law-making powers under Part IV of the Government of Wales Act 2006 as soon as practicable, at or before the end of the Assembly term". The two parties agreed "in good faith to campaign for a successful outcome to such a referendum" and to set up an All-Wales Convention to prepare for such a successful outcome.
