The Socialist (SLP newspaper)
The newspaper was set up by James Connolly in 1901. He was its first editor, after which George Yates took over. During Yates' editorship, it was the focus of the De Leonists within the Social Democratic Federation (SDF). After writing an article critical of the SDF Executive in 1903, Yates was expelled, and the supporters of The Socialist founded the SLP.
In 1904, Yates resigned; by the early 1910s, it was edited by John William Muir; John Smith Clarke was editor for a time, while this role was later taken on by Arthur MacManus, who from 1919 to 1920 was joint editor with Tom Bell. Publication continued until at least 1924.
