The Suffolk Coastal MP Therese Coffey says the problems of the East of England Ambulance Service are "just about budget."
Ms Coffey said it is entirely to do with "management, governance and leadership."
A hard-hitting report on the problems of the East of England Ambulance Trust is calling for more paramedics and more ambulances on the road.
The latest inquiry and report was conducted by Dr Anthony Marsh on behalf of the NHS Trust Development Authority.
Dr Marsh, who is chief executive of West Midlands Ambulance Service NHS Foundation Trust, wrote:
"There is a feeling across the organisation that the trust board does not listen...the board have only recently accepted that there is a shortage of front line ambulance crews within the trust yet managers state they have been raising this for some time."
The Witham MP Priti Patel has responded to the publication of the Governance Review into the East of England Ambulance Service Trust by calling for the Trust's non-executive directors resign and a new Board to be established.
Ms Patel said: "This damning report has demonstrated that the Trust's Board has been failing for many years and their lack of leadership and competence has put patients' lives at risk."
"The non-executive directors who have let patients down should do the decent thing and step down."
