'The pregnancy is in its very early stages,' says royal spokesperson
DUCHESS KATE, confirmed to be pregnant earlier today, has been rushed to hospital suffering from acute morning sickness.
The Duchess is likely to to stay at the King Edward VII hospital in Marylebone until the end of the week.
"The Duchess was admitted this afternoon to King Edward VII Hospital in Central London with Hyperemesis Gravidarum [morning sickness]," read a statement on the Duchess' and husband Prince William's website.
"As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter."
When the baby is born in the summer of next year, it will lie third in line to the throne after granddad Prince Charles and dad Prince William and is likely reign into the 22nd century.
Speculation the duchess - who was known as Kate Middleton before her marriage in April 2011 - could be pregnant was sparked last week when, on a visit to Cambridge, William accepted a gift of a babygro with 'Daddy's little co-pilot' and a picture of a helicopter on it.
The motif is a reference to William's RAF search and rescue pilot career.
"I'm delighted by the news," said Prime Minister David Cameron.
"They will make wonderful parents."
Opposition leader Ed Milliband echoed the PM.
"Fantastic news for Kate, William and the country," he said.
"A royal baby is something the whole nation will celebrate."
