Sefton Central Labour MP Bill Esterson says that a new surgery should be allowed to open in Hightown to address patients fears about the quality of service.
The MP said he has been "blown away" by the level of support for the plan, which would allow a surgery in Formby to open a satellite operation in Hightown for patients who live in the village but are registered in Formby.
The plan to open a new surgery follows concerns raised about the lack of full time GPs and the delays in gaining an appointment at the existing surgery, run by SSP Healthcare.
Bill said: "Many, many patients who live in Hightown have told me they have left the GP practice there because they cannot get an appointment and they are fed up with the lack of full time GPs.
"Some of those patients now go to The Village GP practice in Formby and the Village Practice is asking NHS England if it can set up a new part time surgery in Hightown for patients who live there.
"This seemed like a good idea, so I asked the parish council to find out whether residents in Hightown supported the idea. The answer was an overwhelming yes.
"I was already worried by the concerns raised with me about the poor service available at SSP’s surgery so having an alternative for patients seemed like a good plan."
The Labour MP said his primary goal was to ensure that people in Hightown got the best possible service.
Bill said: "Having a second surgery in Hightown may put pressure on SSP Healthcare and if does that is fine with me. I want to see the best GP service for my constituents and I am happy to support the parish council and the pharmacist, Ellis Hall-Lyon who have all been involved in this proposal.
"If it leads to an improved service by SSP, so much the better. If not, patients will then have a better choice of GP practice.
"There are many elderly and disabled residents in Hightown who are struggling to get appointments so I hope that NHS England agrees to the plan and we see the improvements which people in Hightown need.
"I shall also be asking constituents who use SSP’s other surgeries about their experience of the service at those surgeries and if services are not good enough, I shall be exploring how they can be improved.
"My Labour colleague, Andy Burnham has already pledged that Labour will guarantee a GP appointment in 48 hours if we win the election next year. But in the mean time, I am determined to fight for the best possible service for patients in Hightown and across my constituency."
