One Wales

One Wales (Welsh: Cymru'n Un, pronounced [ˈkəmrɨn ˈɨn]) was the coalition agreement for the National Assembly for Wales between Labour and Plaid Cymru agreed to by Rhodri Morgan, First Minister of Wales and leader of Welsh Labour, and Ieuan Wyn Jones, leader of Plaid Cymru, on 27 June 2007. It was negotiated in the wake of the preceding National Assembly election which resulted in a large Labour plurality, but no majority. Labour and Plaid Cymru approved the document in separate votes on 6 and 7 July, respectively.

On 3 May 2007, Labour won 26 of 60 seats in the 2007 National Assembly for Wales election, four short of an effective majority of 30 (see Speaker Denison's rule for an explanation of why this is so). Originally, commentators had predicted a Labour-Welsh Liberal Democrats coalition, after a previous coalition which had lasted from 2000 until 2003. Liberal Democrat leader Mike German, who had served as Deputy First Minister of Wales in the previous coalition, favoured the deal, which would have given the Government a majority of four. However, concerns within his party about propping up a weakened Labour party prevented such an agreement. An alternative option, the so-called "rainbow coalition" of Plaid Cymru, the Liberal Democrats and the Conservatives, was negotiated between the leaders of those parties in mid-May, but was rejected at a Liberal Democrat special conference vote on 23 May. The new Assembly formally opened two days later with no clear majority, and Rhodri Morgan was elected First Minister unopposed at the head of a minority government.
