From Monday 10th June's Telegraph
Summary from the article
The Duke of Edinburgh is today expected to receive his first visitor since going into hospital, when the Queen drops in to wish him a happy birthday.
The Dukehas been too tired to accept any visitors since he had an exploratory operation on his abdomen on Friday.
If his doctor gives his approval, the Queen will visit .. on Monday
Aides said the Duke remained “comfortable” in the London Clinic where he is recovering from his operation, which was carried out under general anaesthetic.
He is awaiting the results of tests carried out during the operation, which are expected to be available in the early part of this week, before doctors decide whether any further surgery or other treatment is necessary.
If the Queen does arrive, she is likely to be the Duke’s only visitor, as sources suggested he is unlikely to have enough energy yet to receive several wellwishers.
The Prince of Wales will not be able to visit as he is currently in Scotland. Princes William and Harry are also understood to be working at their military bases, meaning they will not be able to see their grandfather.
A royal source said: “Nothing has been decided yet about visitors but it may be that the Queen will visit in the afternoon after she returns from Windsor.
“The golden rule where the Queen is concerned is that she doesn’t want to disrupt the work of the hospital at all, so she will be guided by the doctors looking after the Duke.
“It all depends on the hospital and it depends on whether he is up to it.
“As far as his condition goes, nothing has changed at all, he is still comfortable and he is still recovering from his operation.”
