Campaigners staged a protest in London today over plans for a new retail park in Leighton Buzzard - on land currently owned by the Church of England.
People living in the Bedfordshire town along with traders are opposing the proposals for Grovebury Road.
They fear it will take trade away from Leighton Buzzard's town centre and say it could lead to the closure of many shops and local businesses.
The protesters have criticised the Church Commissioners, the body which looks after the assets of the Church of England.
David Prior, from LB First, a group representing residents and high street traders, said: "It's a very old market town. It's got a very long tradition of traders and high street trading, and I think the local people want it to remain that way."
Plans for the £15m shopping development have been approved by Central Bedfordshire Council who say it will benefit the town and the local community.
Councillor Nigel Young said: "This planning permission is strictly controlled. It's for bulky goods - that means it's not small things that are sold on the high street. It will attract new people to Leighton Buzzard and I believe that, when they've visited the retail park, they'll go into the beautiful high street that Leighton Buzzard has and they'll shop, and they'll eat, and they'll drink in local shops."
Also at today's protest was Canon Grant Fellows from the town's All Saints Church.
He said: "I care very passionately about what's going on in our town, and I want to make sure the Church Commissioners hear that there is concern and that they will respond carefully and thoughtfully."
The Church Commissioners have said they take their obligations seriously and believe the development has a number of benefits.
The plans for the retail park are now under judicial review.
Developer the Claymore Group said it was disappointed there would now be further delays, adding that the local residents they had spoken to had been "overwhelmingly supportive".
Protesters say they do not want the development to go ahead and are prepared to fight it all the way.
