The 1979 United Kingdom general election in Wales saw the Labour Party win the most votes and seats in Wales.[1]
The Labour party won the most votes in Wales, although the Conservatives won most votes UK-wide.
John Morris, Baron Morris of Aberavon was under the impression that Prime Minister James Callaghan would call a general election in the autumn of 1978, but called it off. A Welsh devolution referendum was held in March 1979, two months prior. A Welsh Assembly was rejected, with regional distrust as a potential factor.[2]
