Labour Party support in Wales 1900 to 1979
Support for the Labour Party in Wales from 1900 onwards could have only been at the expense of the Liberal Party in Wales. As the working class in South Wales became more politicised, so the Labour Party prospered. Miners and steel workers formed the backbone of support for the Labour Party between 1900 and 1979 and South Wales became a heartland of Labour support.
