Brighton MP Caroline Lucas has shared her delight at the news Royal Sussex County Hospital will receive a £400m investment.
She said: "This is fantastic news for the city and a real success for the cross-party community campaign.
"Brighton and Hove deserves a 21st century hospital and a strong NHS that puts the public first. We've worked so hard for this essential redevelopment and I will be keeping up the pressure to ensure that there are no more unnecessary delays from the Treasury as the project goes forward."
An investment of £420 million of investment into the Royal Sussex County hospital in Brighton has been announced by the Government.
It follows a two-year campaign by Simon Kirby MP. The hospital's current buildings are some of the oldest in the health service and date back to the 19th Century.
The 753-bed trust provides a full range of surgical support for major trauma and emergencies. The age of the buildings is beginning to have an impact on patient care.
Under the redevelopment programme, old buildings on the site will be demolished and replaced with new ones with modern facilities. The number of beds will increase by 100 and the neurosciences and cancer centres will both be improved.
A government decision is expected on multi-million pound plans to rebuild one of the region's biggest hospitals.
Parts of the Royal Sussex County Hospital in Brighton date back almost two hundred years. Health chiefs want to knock it down and replace it with a state-of-the-art building. It would cost four hundred and twenty million pounds.

The Care Quality Commission told Brighton and SussexUniversity Hospitals NHS Trust that the hospital failed to meet four of thenational standards.
Ian Biggs, Regional Director of Care Quality Commission in the South, said: "Patients are entitled to be treated in services which are safe, effective, caring, well led, and responsive to their needs, and where a service is failing on any of these grounds, action is needed."
The Trust has told us that it has already taken action to improve care and treatment for its patients. We will return unannounced in due course to check that it has made the changes required."
While the report found staff were dedicated, it also saw patients were not treated with dignity especially in the emergency department.
