The by-election was caused by the elevation to the peerage of the sitting Liberal MP, Joseph ‘Jack’ Pease.
[1] The Rotherham Liberals adopted Arthur Richardson as their new candidate.
Richardson had been Lib-Lab MP for Nottingham South from 1906 until January 1910.
[2] Richardson immediately declared his position as being in favour of the successful prosecution of the war and the defeat of German militarism.
[3] No nominations were received from the other parties, who were apparently content to honour the wartime electoral truce and Richardson was therefore returned unopposed.
