Some 400,000 surgical gowns ordered from Turkey do not meet British safety standards, BBC reported on Thursday, citing the UK government.
Up to half of the personal protective equipment (PPE) order was flown to the UK by the RAF last month, but has not been given to NHS workers and is now stuck in a warehouse.
The prime minister’s spokesperson said the NHS was speaking to the supplier about getting replacement gowns.
They said if replacements were not possible it would seek a refund.
But speaking earlier on Thursday morning, a spokesman for the Turkish company that supplied the goods said they had not received any complaints.
Mehmet Düzen, from Selegna Tekstil, told the BBC the company had not had any communication from the NHS, the British Embassy in Ankara or British government officials complaining about the quality of its gowns.
“The fabric we supplied was certified. All the goods were certified,” he said, adding that they were ready to respond if there was a mistake.
