FURIOUS health campaigners, protesting over the loss of hospital services, have asked The Prime Minister to step in after lambasting NHS officials for failing to carry out an investigation they say was promised to them.

The protesters, which include Marlow People's Action Group, wrote this week to David Cameron and Health Secretary Jeremy Hunt asking them to deal with health bosses severely.

The letter, also from Save our Hospital Services and Bucks 50+ Forum, claims that previous Health Secretary Andrew Lansley's instructions to senior NHS chiefs for a probe have been ignored.

Campaigners, including Terry Price, met Mr Lansley in Parliament in 2012, with Wycombe MP Steve Baker, to discuss key concerns, principally, the loss of Wycombe's A&E to Stoke Mandeville.

The now disbanded South Central Strategic Health Authority was asked investigate the group's complaints and report to him direct, but have failed to do so, Mr Price said.

Mr Price, a pensioner from Marlow, said: "I think its both anger and frustration, they've taken no notice whatsoever of an instruction from the Health Secretary.

"They've disregarded it. I'm more than angry, it's an absolute scandal and there's no accountability.

"This so called report has run roughshod over everything. We want answers."

The letter to Mr Hunt and Mr Cameron reads: "In view of the recent serious problems relating to the National Health Service in the United Kingdom, coupled with the recent recommendations contained in the Robert Francis QC report we feel most strongly that you should be aware of what is happening in the county of Buckinghamshire.

"I am sure that you will agree that this degree of conduct is totally unacceptable and should be dealt with the severity which it deserves."

The campaigners said consultations about further structural changes to health services, which led to the Emergency Medical Centre at Wycombe being downgraded to a minor injuries unit, were flawed and had ignored a 40,000 strong petition against changes.

Correspondence did come from the NHS official, charged with investigating, just after the group's complaint was about to be lodged this week, but campaigners said it was merely a narrative of events of which we were already aware of and not a proper report.

It was also not sent to The Health Secretary, they pointed out.

The Department for Health said it had no record of any letter being received - although this may simply mean it has not been logged yet - and so could not comment on any action which it may prompt.

The NHS South of England referred the BFP to The Chiltern Clinical Commissioning Group, which became operational in April this year. It said it would be happy to meet the campaigners to discuss their concerns.
