Duchess of Cambridge pregnant with second child

The birth date of the second child of Britain's Prince William and his wife Kate Middleton has been announced. Royal baby number two is due to be born in April.

The couple announced last month that Kate was expecting a second child to join Prince George who was born in July last year, but no date for the birth was disclosed at the time.

In the statement from William's office, it also confirmed that Kate is still suffering from acute morning sickness. The condition has caused her to cancel a number of official engagements.
