According to the Daily Mail, the government department has been accused of being secretive and stopping legitimate attempts to obtain a copy of the certificate.
Had the Queen died in England there would be no need to release an official cause of death since the Registration Act of 1836 does not apply to monarchs.

But as she died in Scotland under the Registration of Births, Deaths and Marriages (Scotland) Act of 1965, all deaths must be registered within seven days - and this includes the submission of a death certificate to a registrar.
As such, when Prince Philip passed away in April 2021 at the age of 99, no announcement from the Palace was made. One month later, it emerged that his cause of death had simply been recorded as "old age" by the head of the royal medical household, Sir Huw Thomas.

The Queen's death on 8 September has been simply described as "peaceful" by the Palace.
