1912 Manchester South by-election

[1] The constituency returned one Member of Parliament (MP) to the House of Commons of the United Kingdom, elected by the first past the post voting system.

The Liberal MP for Manchester South, Sir Arthur Haworth was appointed a Lord Commissioner of the Treasury.

He had not stood for parliament before, though in December 1910 he was chosen as Conservative candidate to contest the constituency of Manchester South at the general election.

A vigorous campaign was held, with the main issues being woman suffrage with the Parliamentary Franchise (Women) Bill soon to be debated, Irish Home Rule (the Third Home Rule Bill was currently being debated in parliament) and National Insurance, which had been introduced by the Liberal Government the year before.

At the 1918 general election, Haworth was Liberal candidate for Manchester Exchange but failed to make a return to parliament.
