Doctors say they are overwhelmed by the response from the public to their campaign against a new health centre destined for Hemel Hempstead.
So far more than 3,200 people have registered their resistance to the centre, which GPs say will spell closure for existing surgeries and provide a worse service to patients.
A total of 1,200 people have signed an online petition and a further 3,0
00 have filled in slips on leaflets.
The Beds and Herts Local Medical Committee, which is coordinating the campaign, said surgeries are also collecting signatures which have yet to be fed into the tally but patients are 'signing in droves'.
The GP-led health centre will be open to anyone 12 hours a day and 365 days a year in a town centre location.
It is part of a nationwide government initiative to make it easier for people to see a doctor.
GPs say they are already opening at earlier and later hours and the new clinic is an expensive 'white elephant'.
The centre is due to open in March next year but doctors fear it will draw patients from existing surgeries, making them unviable, and offer a less personal service.
A tendering process is currently under way to decide who will run the centre and multinational companies as well as some local GPs have submitted bids.
Mark Brownfield, chair of the Hemel Hempstead and District Locality Forum, which represents family doctors, said: "We've had an enormous response.
"We've been shifting an awful lot of those leaflets.
"People are mentioning regularly that they want to do something."
