The Duke and Duchess of Cambridge are expecting their third child

The Queen and members of both families are delighted with the news.

As with her previous two pregnancies, The Duchess is suffering from Hyperemesis Gravidarum. Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children's Centre in London today. The Duchess is being cared for at Kensington Palace.

Notes to Editors
Hyperemesis Gravidarum is very acute morning sickness, which may require supplementary hydration, medication and nutrients.
