The Duke and Duchess of Cambridge are expecting their third child, Kensington Palace has announced.

Prince Williams and Katherine, 35, who already have a son and a daughter under the age of five – will have a new baby by April or May next year.

The Queen and members of both families are said to be “delighted with the news.”

A statement released from the palace said “As with her previous two pregnancies, the duchess is suffering from hyperemesis gravidarum, or severe morning sickness.

“Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today.”
