Milton Keynes A&E is set to receive £2.7 million in government funding to deal with any additional demand on services this winter.
The announcement has been welcomed by city MPs Mark Lancaster and Iain Stewart who launched the campaign with the Citizen for an expanded A&E.
Speaking in the House, MP Iain urged the health secretary to look again at the case for an expanded A&E given the city's increasing population.
The health secretary responded by praising the campaign and committed to looking at a long-term solution for the city's A&E because he recognised that there are long-term pressures.
Commenting afterwards, Mr Stewart said: "The city's A&E has made remarkable improvements given its constraints, thanks to the dedicated staff. I am pleased with this additional funding because it will help staff make even greater progress in the quality of care they deliver."
North Milton Keynes MP Mark Lancaster, who recently wrote to the health secretary on the same issue added: "This additional funding will go a long way to help Milton Keynes A&E with the increased demand in its services during the winter months. Combined with the recent announcement of funding for113 extra nurses and health care assistants at the hospital, I am pleased to see that the government are taking the needs of our hospital seriously."
