Stoke North MP Joan Walley has urged the Prime Minister not to forget that University Hospital North Staffordshire will have to be funded to take on extra patients from Stafford in future.
Jeremy Hunt MP has agreed to dissolve the scandal-hit Mid Staffordshire NHS Foundation Trust.
Under today's announcement, Stafford Hospital could still retain consultant-led maternity services after the Health Secretary agreed for NHS England to carry out a review into the issue.
The original plan from administrators had been for maternity services to close. However, this was later amended to the creation of a midwife-led unit. Mr Hunt has now agreed for a review of that decision.
The changes recommended following this independent process, supported by local doctors, will secure the safe and high quality services that the people of Stafford deserve having endured years of uncertainty and failures in care.
90 per cent of patient visits will continue locally, with a minority of services eventually being moved to neighbouring hospitals once the local NHS is satisfied there is sufficient capacity.
I want Stafford to be a proper district hospital that continues to meet the needs of patients nearby, including for emergency care and births.
Health Secretary Jeremy Hunt has agreed to dissolve the scandal-hit Mid Staffordshire NHS Foundation Trust and move key services to neighbouring hospitals.
Sue Hawkins, of the campaign group Support Stafford Hospital, said they expected that Jeremy Hunt "probably will" dissolve the trust.
She said they hoped that Mr Hunt would reflect some of their concerns in his announcement.
She told BBC Breakfast the concern was primarily over obstetrics.
A simple birth can change to needing a Caesarean section very quickly. Are those patients going to make it in time 18 miles up the road?
Infrastructure - the M6 - often accidents, often shut, Stafford has got a very poor network of roads. We get gridlocked very easily. We are seriously concerned about safety.
She said 50,000 people had marched in a small town of only around 60,000 - although the surrounding area is bigger - showing their support for retaining these acute services.
"Treatment would obviously move to neighbouring trusts but we have a very high proportion of elderly. What is going to happen?"
Campaigner Julie Bailey, whose mother died at Stafford Hospital, has said that she will not be making a statement today, despite the Health Secretary preparing to announce his decision on the future of the scandal hit NHS Trust.
CTNHS will not be making a statement about Mid Staffs 2day, for our own safety. We will support any decision that promotes patient safety
Health Secretary Jeremy Hunt will be making a written statement in the House of Commons later to announce his decision on if the scandal-hit Mid Staffordshire NHS Foundation Trust should be dissolved.
The future of struggling Stafford Hospital hangs in the balance today as the deadline looms to make major decisions over its future.
Health Secretary Jeremy Hunt has until the end of today to decide whether to demand the Trust Special Administrators (TSAs) for Mid-Staffordshire NHS Trust make changes to their recommendations for action.
The TSAs controversially recommended the dissolution of Mid-Staffordshire as its own trust, and said Stafford Hospital should move under the care of University Hospital of North Staffordshire NHS Trust. Cannock Hospital would be taken over by the Royal Wolverhampton Hospital NHS Trust.
If the TSAs' recommendations are not altered, the changes are expected to take place in the autumn.
