The constituency has three main population centres, namely Kirkham/Wesham, Lytham St Annes and Freckleton. Kirkham, Wesham and Freckleton are small towns with some light industrial development and have a considerable Labour vote, but Lytham and St Annes are comfortable seaside resorts, favoured by families and retired couples, and along with the more rural parts of the seat, are safely Conservative.
The Borough of Wyre wards of: Breck; Hardhorn with High Cross; Tithebarn.[4]
The constituency will be expanded to bring the electorate within the permitted range by transferring in the three Borough of Wyre wards which constitute the town of Poulton-le-Fylde, transferred from the (to be abolished) constituency of Wyre and Preston North. The small part currently in the City of Preston will be transferred to a revised Preston constituency.
