THE UK Government is scrapping Public Health England and replacing it with an organisation headed by a Tory peer.

The National Institute for Health Protection will respond to health threats including infectious diseases, pandemics and biologic weapons, Matt Hancock announced.

It will be headed up by Baroness Dido Harding, who has overseen the implementation of England's highly criticised track and trace system.

The body will begin work immediately but will become formally operational next spring. It will merge the Covid response work of PHE, NHS Test and Trace and Joint Biosecurity Centre in the "first step towards becoming a single organisation", the Department of Health and Social Care (DHSC) said.

The Tory Government has faced criticism over the prospect of breaking up the PHE, which was established in 2013 under Conservative health reforms, in the middle of a pandemic.

Ministers have also been accused of using PHE as a "scapegoat" for other failings in the crisis.

And commentators have called into question the appointment of former Talk Talk boss Baroness Harding.

Speaking at the Policy Exchange think tank, Hancock said: "To give ourselves the best chance of beating this virus and spotting and tackling other external health threats now and in the future, we need to bring together the science and the skill into one coherent whole.

"So, today, I am announcing that we are forming a new organisation, the National Institute for Health Protection.

"The National Institute for Health Protection will have a single and relentless mission: protecting people from external threats to this country's health.

"External threats like biological weapons, pandemics and, of course, infectious diseases of all kinds."

Hancock said the new institute will play a role across the UK and be dedicated "to the investigation and prevention of infectious diseases and external health threats".

He added: "It will be dedicated to the investigation and prevention of infectious diseases and external health threats, that'll be its mission.

"It's conceived amid crisis but it will help maintain vigilance for years to come."

The Health Secretary insisted he had "every confidence" that the new organisation will be "world-renowned" and there was "no time to lose" in setting it up.

The National: Matt Hancock

But leading health think tank The King's Fund said PHE "appears to have been found guilty without a trial."

It is expected that a consultation will be launched about PHE's other work going forward.

The health body holds a wide remit of responsibilities including driving down health inequalities and improving the nation's health by tackling issues such as obesity and smoking.

PHE boss Duncan Selbie has been ousted as head of the organisation in the reshuffle, with Michael Brodie, currently head of the NHS Business Services Authority, appointed interim chief executive of PHE.

Selbie, who is highly regarded in the public health community, is to become a senior adviser on global and public health to DHSC.

He said it had been an "honour and a privilege" to lead the organisation, adding: "I could not be any prouder of what PHE has achieved since 2013 in protecting the country from infectious diseases and environmental hazards and in improving the health of the people from reduced smoking rates to tackling poor air quality and obesity and much else.

"PHE's work on the pandemic in the early stages and since stands testament to the professionalism and unremitting hard work of my colleagues and bought precious time for the NHS and Government to prepare."

In a statement, Baroness Harding said: "The changes announced today are designed to strengthen our response, and to radically ramp up our fight against this disease, whilst also protecting PHE's essential work beyond Covid that is so important for the nation's health."

Commenting on the news, Layla Moran, LibDem MP and chairwoman of the All Party Parliamentary Group on Coronavirus, said: "The lack of public scrutiny or transparent recruitment process for such a crucial appointment is appalling.

"This decision should have been debated and scrutinised in Parliament, instead it was announced at a right-wing think tank without a single question allowed from the media.

"Given we still don't have an effective test, trace and isolate system, this feels like a reward for failure."

Labour's shadow public health minister Alex Norris added: "The structural reorganisation that Matt Hancock has announced today is a desperate attempt to shift the blame after years of cutting public health budgets, when the real shift we need is towards an effective local test and trace system that delivers mass testing and case finding.

"Matt Hancock himself was responsible for Public Health England and in setting PHE's priorities last year, ministers didn't even mention preparing for a pandemic.

"This announcement gave no answers on what will happen to other vital areas of public health like addiction, obesity and sexual health either.

"We went into this pandemic with health inequalities widening and life expectancy going backwards for the poorest.

"We have seen that Covid-19 has thrived on these inequalities, disproportionately impacting the poorest and black, Asian and minority ethnic communities.

"A strong public health sector is needed more than ever."

Richard Murray of The King's Fund, commented: "PHE appears to have been found guilty without a trial.

"It is unclear what problem government are hoping to solve by carving up PHE and redistributing its responsibilities.

"Undoubtedly, there are questions to be answered about England's handling of the Covid-19 crisis, but the middle of a pandemic is not the time to dismantle England's public health agency.

"History is littered with reorganisations of the health system that are costly, time consuming and demoralising for staff.

"It is risky to undertake such a shakeup whilst the nation is still grappling with Covid-19, ahead of an anticipated winter spike in demand for health services and with the looming threat of a second wave of the virus."

Nigel Edwards, chief executive of the Nuffield Trust think tank, added: "The Government risks making a major misstep by dismantling its own Public Health agency at such a crucial time, creating a huge distraction for staff who should be dedicating themselves to the next stage of the pandemic."

Professor Maggie Rae, president of the UK Faculty of Public Health, added: "Whilst the new organisation will exist to protect the public from external threats to health, it is so important that we have an effective, well-resourced, public health system which will improve health as well as protect it.

"Government needs to recognise the importance of all functions and domains of public health - not just health protection."

In other developments - - The number of British adults suffering depression has almost doubled compared to before the pandemic, according to the Office for National Statistics (ONS).

- Data from official agencies across Britain show that over 57,000 deaths involving Covid-19 have now been registered in the UK.

- A separate ONS data series showed that only around 28% of people testing positive for Covid-19 reported any evidence of symptoms at the time of their swab test or at either the preceding or subsequent tests.
