Devolution continued to form part of the platform of the Labour Party which won power under Tony Blair in May 1997. In September 1997, the Scottish devolution referendum was put to the Scottish electorate and secured a majority in favour of the establishment of a new devolved Scottish Parliament, with tax-varying powers, in Edinburgh. An election was held on 6 May 1999, and on 1 July of that year power was transferred from Westminster to the new Parliament.
