Media wait outside the King Edward VII hospital.
The Duchess of Cambridge is "continuing to feel better"
and she and the Duke are immensely grateful for the good wishes
they have received, St James's Palace says.
Kate is spending a second night in a private hospital where
she is being treated for a severe form of morning sickness
after revealing her pregnancy yesterday.
William spent most of the day at the bedside of his wife, who
is likely to be on a drip so she can receive fluids
intravenously to combat the effects of dehydration caused by
the condition known as hyperemesis gravidarum.
Her illness could indicate she is having twins as mothers
carrying two babies have a greater chance of developing the
severe morning sickness.
But while there is concern for the royal couple, there is
excitement across the UK and beyond, with messages of support
sent from leading figures both at home and abroad.
A St James's Palace spokesman said: "The Duchess of Cambridge
is continuing to feel better.
"She and the Duke are immensely grateful for the good wishes
they have received.
"She will remain in hospital at present and will continue to
be treated for hyperemesis gravidarum."
