Reform UK Great Grimsby and Cleethorpes

Reform UK is standing in Great Grimsby and Cleethorpes as part of its campaign to contest all 650 constituencies at the next general election. The party — which is polling at over 25% nationally — is rapidly building its local branch network, with Great Grimsby and Cleethorpes among the constituencies where activists are organising.

The current MP is Melanie Onn, who has held the seat for the Labour since the 2024 general election. Reform UK is targeting seats across England and Wales as it seeks to convert its national poll ratings into parliamentary representation.
