Hundreds of residents have signed a petition in a campaign to keep their village post office where it is.
The Post Office wants to relocate Upwell Post Office into the nearby G&B Superstore.
But villagers don’t want to see it moved and more than 400 signed a petition fighting the plan that was handed to local MP Elizabeth Truss.
The Post Office says the move will provide a more modern open-plan environment, an extra 70 hours of Post Office services per week and all day opening at weekends.
But villagers believe the plan is wholly unsuitable.
Parish council chairman Prue Lester said there were concerns including lack of privacy carrying out transactions at an open counter post office in a busy convenience store and loss of services such as Transcash/Girobank business banking and reduced personal banking facilities, including no longer being able to pay in cheques.
The new facility would not be able to hold undelivered mail that needs a signature or parcels for collection, meaning customers would have to go to Wisbech to collect Royal Mail parcels and Cambridge for Parcel Force items.
She said increasing the number of people using G&B Superstore would also exacerbate parking problems on a more narrow stretch of Town Street – heavily used by HGVs and agricultural machinery – and there is a lack of space inside the store for wheelchair users and children’s buggies.
Mrs Lester added: “Longer opening hours are not wanted or necessary. Late night disturbance is a concern and extended hours postal services are already available in Outwell, half-a-mile up the road.
“All in all, parishioners are very happy with the current service provided.”
The Post Office is running a public consultation on the proposal until Tuesday, March 3.
