THERE is growing speculation that the Duke of Edinburgh is undergoing end-of-life care in hospital.

Charles arrived at King Edward VII's hospital in London a little after 3pm on Saturday February 20 to visit his father, aged 99, who had been admitted on the evening of Tuesday, February 16.

Official sources have said the hospitalisation is a "precautionary measure" and is not connected to Covid-19.

The Queen’s husband, who had his first Covid jag in January, reportedly walked inside the hospital unaided, and was not taken by ambulance.

On Friday, it was reported that Philip was likely to stay in hospital over the weekend and into next week for rest and observation.

However, Prince Charles’s visit has stoked speculation that the Duke of Edinburgh may be in dire health.

The King Edward VII Hospital website says that visitors will only be allowed after direct discussion with the Matron’s Office, and only under two sets of circumstances.

The first of these is that “one regular carer will be allowed for patients with additional needs e.g. dementia, learning disabilities”.

The second is that “patients receiving end of life care” may receive a single visitor at a time.

A Buckingham Palace source told the BBC that Philip is in hospital due to “an abundance of caution".

Earlier today, it was announced that Princess Eugenie and husband Jack Brooksbank have named their newborn son August Philip Hawke Brooksbank, in tribute to the Duke of Edinburgh.

It is understood the couple chose the name August after Queen Victoria’s consort Prince Albert, who had Augustus as a middle name.

Eugenie posted on Instagram: “We wanted to introduce you to August Philip Hawke Brooksbank. Thank you for so many wonderful messages. Our hearts are full of love for this little human, words can’t express. We are excited to be able to share these photos with you.”
