Prince Philip was first admitted to a London hospital on February 17 โ he has remained there since.
Now, the Palace has shared a further update on Philipโs condition, explaining in a statement that he is suffering from an infection, as well as a pre-existing heart condition.
As he has continued treatment, the Duke has now been moved from King Edward VIIโs Hospital to St Bartholomewโs Hospital in London.
In the statement, the Palace explained: โThe Duke of Edinburgh was today transferred from King Edward VIIโs Hospital to St Bartholomewโs Hospital where doctors will continue to treat him for an infection, as well as undertake testing and observation for a pre-existing heart condition.โ
The statement continued: โThe Duke remains comfortable and is responding to treatment but is expected to remain in hospital until at least the end of the week.โ

Prince Philip has been in hospital for just under two weeks now.

It seems his pre-existing condition has continued to cause complications โ his new hospital is known for its thorough treatment for cardiovascular issues.

The Prince has a pre-existing heart condition which has required monitoring.

Today, she even took part in a special unveiling ceremony of her own statue here in Australia.
Appearing in high spirits in a soft pink ensemble, the Queen joined in a video call with the Governor of South Australia, His Excellency the Hon. Hieu Van Le and the Premier Steven Marshall as they unveiled the statue, which sits outside Government House in Adelaide, South Australia.
Itโs encouraging to see the Queen go about her work as per usual โ so hereโs hoping Philipโs hospital stay doesnโt last much longer and heโs reunited with his wife soon enough.
