A referendum was held in 1979 under a Labour government which stipulated that a Scottish Assembly would come into being if the referendum had been supported by 50% of votes cast plus a controversial rule whereby at least 40% of the electorate had to vote in favour. Although 51.6% voted in favour, this was only 32.9% of the electorate so the Assembly was not brought into being. Shortly afterwards, the predominantly anti-devolution-led Conservative Party won the 1979 general election.

That government put devolution to one side but it was a policy area that remained on the agenda of the Labour Party. A Campaign for a Scottish Assembly was formed afterwards to continue the campaign. They brought together a committee of "prominent Scots" who drafted the document "A Claim of Right for Scotland". The "Claim" was published in 1988 and signed by most Scottish politicians, local councils, trade unions and churches. It was agreed to form a Scottish Constitutional Convention, made up of existing MPs and councillors.
The Labour Party included the establishment of a Scottish Parliament in its manifesto for the 1997 general election, which they won with a landslide majority of 179.
