Hundreds of people signed up to Bill Esterson's campaign to save Maghull Ambulance Station in Lydiate - all within hours of the online petition going live.
The Labour MP launched the campaign after news broke that North West Ambulance Service was planning to close the station on Kenyons Lane.
In a letter to the MP this week, North West Ambulance Service acting chief executive Bob Williams said they planned to close the Lydiate station and relocate the emergency ambulance currently based there in the new Bootle & Netherton Fire Station at Buckley Hill.
Mr Williams goes on: "In the current financial climate, it is imperative that we make savings."
Bill said he was extremely concerned that the move was clearly motivated by Tory-Lib Dem Government cuts.
Bill said: "More than 200 people from Maghull and Lydiate signed the petition on the first day of it going live online, which just goes to show the strength of feeling locally against the closure plans.
"North West Ambulance Service clearly state in their letter to me that the proposed closure of the ambulance station in Lydiate is as a direct result of the the financial climate they find themselves in because of the Tory-Lib Dem cuts.
"I am always deeply concerned when decisions of this magnitude are being made as a consequence of funding cuts and not in the interests of public safety."
Bill said the Tory-Lib Dem cuts are having an impact on the NHS locally.
Bill said: "Both direct and indirect cuts to the NHS are having a huge affect on the NHS. Cuts directly to funding for local health services affecting the provision across Sefton and Merseyside. And cuts to services in the community are resulting in greater strain on an already under pressure health service.
"Cuts to funding for care in the community, cuts to local services, all imposed by the Tories and Lib Dems, are putting immense pressure on A&E and our hospitals. Instead of conditions being identified early and treated in the community, there is a surge in the number of people having to go to hospital for treatment.
"It is in this climate that decisions, like the decision to close Maghull Ambulance Station in Lydiate, are being taken.
"People are concerned, and that is why so many have added their name to the campaign."
