THE UK Government spent more than £150 million of taxpayers’ money on 50m face masks that cannot be used because they don’t meet NHS safety standards.

The payment was part of a £252.5m PPE deal struck with a UK Government adviser.

The masks, ordered from Ayanda Capital, have ear loops rather than head loops, and there are concerns over whether they are adequate.

The Government has confirmed in court papers that the masks, which are now in the Department of Health and Social Care's (DHSC) logistic chain, will not be used in the NHS.

The Good Law Project and EveryDoctor, which are suing the Government over its Ayanda contract, estimate the 50 million masks would have cost more than £150m.

Labour called for an inquiry into the contract, while the Prime Minister told reporters: "I'm very disappointed that any consignment of PPE should turn out not to be fit for purpose."

He said there were legal proceedings under way so he would not be drawn on the specific example.

Court papers show the Government awarded the £252.5m contract to Ayanda on April 29, with £41.25m payable on commencement to secure the manufacturing capacity.

Ayanda Capital also supplied 150 million masks of another type, which the Government says are unaffected but will be subject to further testing in the UK before any are released for use in the NHS.

The Government also disclosed in court papers that the original approach to sell the masks came from a businessman called Andrew Mills, director at a company called Prospermill, which had secured exclusive rights to the full production capacity of a large factory in China to produce masks and offer a large quantity almost immediately.

The legal document revealed Mills requested DHSC's contractual counterparty should be Ayanda rather than Prospermill, as Ayanda already had an established international banking infrastructure that could be used to effect the necessary payments overseas, whereas Prospermill's own bank had indicated it could take some time to set this up on its own account.

The Government also said in court papers that Mills is an adviser to the UK Board of Trade and a senior board adviser at Ayanda.

Mills told the BBC his position played no part in the award of the contract, the broadcaster reported.

Jolyon Maugham, director of the Good Law Project, said: "Good Law Project wrote to Government on three contracts each worth over a hundred million pounds – with respectively a pest control company, a confectioner and a family hedge fund.

"Each of those contracts has revealed real cause for alarm - including, on Ayanda, that around £150 million was spent on unusable masks. What other failures remain undiscovered?"

Julia Patterson, founder of EveryDoctor, said: "It is horrifying that during the worst crisis in the NHS's history, the Government entrusted large sums of public money in the hands of companies with no experience in procuring safe PPE for healthcare workers."

Rachel Reeves, shadow chancellor of the Duchy of Lancaster, said the case for the National Audit Office to investigate the Government's mishandling of PPE is "overwhelming", adding: "It is astounding that ministers allowed the national PPE stockpile to run down and then spent millions with an offshore finance company with no history of providing vital equipment for the NHS."

LibDem MP and chair of the All Party Parliamentary Group on Coronavirus Layla Moran said a clear strategy for procuring PPE is urgently needed, adding: "The Government has serious questions to answer over this shocking waste of taxpayers' money."

A UK Government spokesman said: "Throughout this global pandemic, we have been working tirelessly to deliver PPE to protect people on the front line.

"Over 2.4 billion items have been delivered and more than 30bn have been ordered from UK-based manufacturers and international partners to provide a continuous supply, which meets the needs of health and social care staff both now and in the future.

"There is a robust process in place to ensure orders are of high quality and meet strict safety standards, with the necessary due diligence undertaken on all Government contracts."

Tim Horlick, CEO of Ayanda Capital, insists the masks are not unsafe or unusable, adding that none of his company's products have ever been rejected by DHSC for any reason.

Horlick said his company supplied DHSC with the masks they requested, approved and ordered, adding that it may be that the internal NHS requirements changed as things were moving very fast at the time.

He said: "In summary the masks met all Government specifications and standards, the masks are not unusable or unsafe and the Government has not wasted any money in purchasing these masks."
