 The Unionist candidate was Bonar Law, former Parliamentary Secretary to the Board of Trade who had lost his seat in the Liberal landslide in the February general election.The Liberal Party candidate was David Williamson, who had also contested the February election.The Conservative majority increased by over 900 votes, which the "Times" attributed not only to Bonar Law's candidature but also to the unpopularity of the Government's Education Bill, suggesting that the Catholic vote, estimated at 700, had gone mostly to the Conservatives as a result.
