Prince Philip

The Duke of Edinburgh will find out today whether he will be forced to spend his 91st birthday in hospital.

The Duke was admitted to the King Edward VII Hospital in central London on Monday suffering from a bladder infection.

Yesterday, grandsons the Duke of Cambridge and Prince Harry paid a visit to the King Edward VII hospital in London, where he is being treated.

Philip had been planning to celebrate his birthday on Sunday privately and is not due to attend his next scheduled engagement until Tuesday, when the Queen hosts a garden party at the Sandringham Estate to mark her Diamond Jubilee.

It is hoped her husband will be by her side at her Norfolk retreat if he has been discharged in time.

It is also hoped he will be able to accompany her to the East Midlands on Wednesday for a two-day visit as part of the Queen’s Jubilee tour of the UK.

Philip’s admission to hospital meant he was forced to miss some of the Jubilee celebrations this week.

He spent Sunday braving the elements for the Thames River Pageant, which doctors suggested might have exacerbated his condition if he did not make enough visits to the toilet.
