The
Representation of the People Act 1918 provided that the constituency was to consist of "Duddeston and Nechells Ward, St Mary's Ward (except the part thereof included in the
Aston Division), and so much of the portion of Aston Ward which is not included in the Aston Division as lies to the west of the
London and North Western Railway". On its abolition by the
Representation of the People Act 1948, the Duddeston and Nechells Wards became part of the
Small Heath constituency, and the St Mary's and Aston wards were transferred in their entirety to the
Aston constituency. ==Members of Parliament ==
