The Queen is under medical supervision at Balmoral after doctors became concerned for her health, Buckingham Palace has said.
"Following further evaluation this morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision," a statement said."
The Queen remains comfortable and at Balmoral."
There are clearly pressing concerns for the Queen's health - much more explicitly put than before and without any reference to this only being about difficulties with mobility.
