It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first past the post system.
The constituency was created as a result of the Report of the Boundary Commission in 1917, when it was recommended to be called "Manchester Collyhurst".
[1] However, when the Representation of the People Bill to give effect to the commission's recommendations was debated in Parliament, the Government accepted an amendment to change the name to Platting.
The constituency was defined as the Collyhurst, Harpurhey and Miles Platting municipal wards of the County Borough of Manchester, together with the part of the St Michael's municipal ward which was not included in the Exchange division.
The St Michael's ward was divided along the Rochdale Road, the small area to the south-west including the High Street area being excluded.
