The Queen has been suffering from pneumonia, Buckingham Palace has confirmed.
Camilla, 77, has been absent from parts of the state visit of the emir of Qatar because of illness, but did join the King and guests for lunch at Buckingham Palace.
The palace, which had previously only described her illness as a viral chest infection, confirmed that it had been pneumonia and that the Queen was suffering post-viral symptoms.
It is understood the Queen has not required hospitalisation since becoming ill.
