NHS bosses who put forward proposals to close Sandwell Hospital's Accident & Emergency department should scrap the plans or resign, an MP has demanded.
Tom Watson (Lab West Bromwich East) said he was furious over proposals to close the A&E and send patients to City Hospital in Birmingham.
He stormed out of the meeting where the suggestion was first raised.
The MP claimed health managers were threatening to break a promise not to reduce services, which was made to residents when Sandwell and City Hospital merged in 2001.
The controversial closure proposal has been drawn up by a body called the 2010 Agency, which was set up to improve health services in the area.
Members of the 2010 Agency include Sandwell and West Birmingham Hospitals NHS Trust, which runs Sandwell Hospital.
Mr Watson said: "I made it very clear when I was first elected four years ago that neither I nor the people of Sandwell would even entertain the thought of our local accident and emergency being closed.
"We will not tolerate the closure of the borough's A&E and we will not take this lying down."
Mr Watson added: "I am calling on whoever is responsible - whether it's Richard Nugent, executive chair of the 2010 Agency, or another bureaucrat - to withdraw the proposal and put the original plans back on the table."
Sandwell Hospital opened a new £18 million accident and emergency centre in April.
Elena Goodyear, programme administrator of Towards 2010, said the proposal was included in one of four options which would be going out for public consultation.
She said: "We will not be recommending it as the best way forward."
