The Liberal–Labour movement refers to the practice of local Liberal associations accepting and supporting candidates who were financially maintained by trade unions.
These candidates stood for the British Parliament with the aim of representing the working classes, while remaining supportive of the Liberal Party in general.
In 1880, they were joined by Henry Broadhurst of the Operative Society of Masons and the movement reached its peak in 1885, with twelve MPs elected.
These include William Abraham (Mabon) in the Rhondda division whose claims to the Liberal nomination were essentially based on his working class credentials.
The Liberal-Labour group finally died out at the 1918 general election, when Thomas Burt (by then Father of the House) and Arthur Richardson stood down.
