Traditionally held in June, the Cartier Queen’s Cup had originally fallen victim to the virus and was forced to be cancelled after mass gatherings were banned. However, organisers of the event, which is one of Her Majesty’s favourite royal engagements, have been working to ensure it still goes ahead at the end of July. One organiser told Richard Eden for the Daily Mail: “We are all determined to go ahead.”

However, despite the rescheduling, the monarch herself is not expected to attend.

Last week the Sunday Times reported that the Queen is set to withdraw from her public duties until at least the autumn.

It is believed to be her longest absence from official duties for her 68-year reign.

While the Queen normally travels to Balmoral for her annual break, she is also set to stay at Windsor Castle for the foreseeable future as the health crisis continues.

The pandemic has seen all royal engagements cancelled for the time being, including the Trooping the Colour in June, the Order of the Garter service and the Queen’s annual garden parties.

There were no gun salutes to mark her 94th birthday this year, as the monarch decided it was not appropriate amidst the pandemic.

The Queen is reported to be in good health and is isolating alongside her husband, Prince Phillip.

Prince Charles, 71, was forced to self-isolate for a few weeks after testing positive for the bug. He has since made a full recovery.

In a rare public speech at the beginning of April, the Queen told the UK it “will succeed” in its fight against the pandemic.

She thanked people for following government rules to stay home and praised those “coming together to help others”.

Speaking from Windsor Castle she said: “While we have faced challenges before, this one is different.”

“This time we join with all nations across the globe in a common endeavour, using the great advances of science and our instinctive compassion to heal. We will succeed – and that success will belong to every one of us.

“We should take comfort that while we may have more still to endure, better days will return: we will be with our friends again; we will be with our families again; we will meet again.”
