The British Socialist Labour Party had been founded in 1903 by Scottish supporters of Daniel de Leon, a leading figure in the American SLP and the IWW.

B. Allen and his supporters mirrored the Chicago section's call for the cessation of political activity which was not channelled through trade unions.

Faced with militant opposition, Singer's organised a postal vote asking staff whether they wished to return to work.

[6] The IWGB remained close to the Detroit-based IWW of De Leon, and when that group renamed itself the Workers International Industrial Union (WIIU), they became the British affiliate and similarly changed their name.

[7] Tom Bell saw the Red Clydeside movement and the Clyde Workers Committee as its most important continuation.
