The election of a Labour Government in 1997 brought devolution back to the political agenda. In July 1997, the government published a White Paper, "A Voice for Wales", which outlined its proposals for devolution, and in September 1997 an elected Assembly with competence over the Welsh Office's powers was narrowly approved in a referendum. The National Assembly for Wales () was created in 1999, with further authority devolved in 2007, with the creation of a Welsh legal system to adjudicate on specific cases of Welsh law. Following devolution, the role of the Secretary of State for Wales greatly reduced. Most of the powers of the Welsh Office were handed over to the National Assembly; the Wales Office was established in 1999 to supersede the Welsh Office and support the Secretary of State.
