Aldridge-Brownhills parliamentary constituency, to which Pelsall belongs, could disappear under new Boundary Commissions plans.
Under cost-cutting proposals, the number of parliamentary constituencies could be cut from 650 to 600.
It means Walsall would lose one MP and the bulk of Aldridge-Brownhills, which is served by the Conservative Richard Shepherd MP, would be transferred to Walsall North.
Walsall South would also include New Oscott, a Birmingham City Council ward, and Sandwell’s Great Barr ward.
If the changes go ahead, the West Midlands will lose five MPs altogether, reducing constituencies from 59 to 54.
