The salary of the boss of the county's ambulance service has been branded "obscene" as it emerged he is racking up a £400 weekly bill on taxis.
Health Minister Dr Dan Poulter said he felt the £232,000 paid to the chief executive of the East of England Ambulance Service NHS Trust (EEAST) Dr Anthony Marsh was excessive.
Dr Poulter said: "There's no doubting that Anthony Marsh is a very skilled man with a lot to offer to the ambulance service... but when you're in a leadership role you have to set an example."
Dr Marsh is also the head of the West Midlands service and took over the East of England remit in January, which brought him £50,000 rise.
The trusts say the dual role brings an overall saving of £130,000 but the minister said this sent out the wrong message.
He earns more than £90,000 more than the Prime Minister.
Dr Marsh also takes a taxi from his West Midlands home to the EEAST headquarters in Cambridgeshire so he can deal with "hundreds" of emails.
Dr Poulter continued: "Effectively Dr Marsh is being paid two salaries at the same time, even though he's only doing half a job for each ambulance service.
"It's obscenely high and a profligate waste of money.
"I'm going to be raising the issue directly with the chairs of the ambulance trusts and calling them in for a meeting to make sure they can explain what they're doing with public money, and explain why they're not prioritising front-line patient care with the money they're given by the NHS and then by the government."
An EEAST spokesperson said: "Since his appointment, Mr Marsh has saved taxpayers approximately £8m of back office functions and management savings to help fund the recruitment of 400 new staff, with more than 120 already having joined the trust, and brought in 147 brand new ambulances and more than 60 rapid response vehicles.
"The organisation has turned a corner thanks to the actions Mr Marsh has put in place."
