William John Stewart (1868 – 14 May 1946) was a Unionist politician in Northern Ireland who formed a Progressive Unionist Association to protest "autocratic" tendencies in the Unionist government and its lack of action on unemployment.
Accusing the Unionist government of displaying "autocratic" tendencies, in April 1937 he formed the Justice for Ulster Committee which proposed limiting office in government to eight years or two parliaments.[2]
In August 1937 he founded the Ulster Progressive Unionist Party. It called for greater action on unemployment and for bringing Northern Ireland up to British standards on housing and social services. Progressive Unionist candidates opposed UUP candidates in elections, but Stewart continued to take the Conservative and Unionist whip at Westminster.[3]
