The world has seen the royal baby for the first time as the future king left hospital with his ecstatic parents this evening, who revealed they had not yet chosen a name.
Prince William and Kate waved and smiled broadly to the waiting cameras as they held their prince on the steps of the private Lindo Wing at St Mary's Hospital in London, 26 hours after he was delivered, weighing 8lbs 6oz.
The Duke of Cambridge followed the steps his parents Charles and Diana took with him 31 years ago, when he was born there on June 21, 1982.
His child is now third in the line of succession, displacing Prince Harry to fourth and the Duke of York to fifth, although he may not become sovereign for half a century or more.
The Duke, Duchess and Baby Cambridge will travel home to Kensington Palace tonight, spending two weeks there while William is on paternity leave.
Huge crowds of well-wishers and journalists from all over the world have been waiting outside the west London hospital ward for weeks, first to be there when Kate went into labour and now as the couple left with her firstborn child..
