Supermarket chains often face a lot of local opposition when they want to open a new store.
But people in Cinderford desperately want a new supermarket, after previous attempts were blocked by the rival Co-op.
Residents in Cinderford are to stage a further protest in favour of a new Asda store later this morning. Last month nearly 200 people joined a demonstration against the local Co-Op's legal challenge against the development.
More than 1,400 people have signed up to a Facebook page backing the plans, which have been supported by Forest of Dean District Council. Mid-Counties Co-Op is seeking a judicial review. The Co-Op has previously seen off plans by Tesco to build in the town. Protesters plan to march at noon.
