 The provisions of the Acts would not come into force unless approved by referendums, and accordingly Scottish and Welsh devolution referendums were held on 1 March 1979.The Welsh assembly was rejected by a majority of voters, while Scottish devolution was supported by 51.6% of those voting, or 32.9% of those on the electoral register.An amendment to the Scotland Act, introduced by government backbencher George Cunningham, had specified that it must have the support of 40% of the entire electorate, and the referendum was lost.
