Sefton Central Labour MP Bill Esterson has said a GP Surgery's plans to slash opening hours in Melling forcing patients to travel miles into Knowsley for care is "totally unacceptable".
The MP was contacted by patients of Waddicar Lane Surgery after they announced opening hours were to be cut to Monday to Friday, 9am to 1pm.
Bill immediately contacted the surgery and made a formal demand for action from the Clinical Commissioning Group, which if the overseeing body for health care in Sefton.
Bill said: "It is totally unacceptable that a GP surgery's hours are cut so drastically, particularly given that this surgery is the only one for miles around and is relied upon by so many people in what is essentially an isolated community.
"For people in Melling who work and want to see a GP, it would be impossible given these reduced hours.
"The three-mile distance between Melling and the proposed afternoon and evening surgery in Kirkby is clearly far too great for many patients, particularly the elderly, to have to travel.
"It is not acceptable and I expect the Clinical Commissioning Group to step in and take action."
Bill said he was also currently investigating whether a GP surgery has the power to decide to reduce its hours without prior approval.
Bill said: "Can it be right that a GP surgery can cut its hours so severely without a full patient consultation and prior approval of the Clinical Commissioning Group.
"I am currently checking the rules to be seen if anything can be done.
"Either way, the people of Melling need urgent action and that is what I am pushing for."
