Royal Baby latest: Kate channels Diana in stunning red dress as family leave hospital

The Duchess of Cambridge wore a long red dress as she and Prince William showed the British public their third child outside Lindo Wing.

She evoked memories of Princess Diana who also wore red as she posed with Prince Charles and a newborn Prince Harry outside the same wing in 1984.

Kate, like Diana, looked radiant as she showed off the newest member of the family - who even gave his first royal wave to the adoring crowd. 

William and Kate did not respond to questions but waved and smiled as they posed for photographs with their third Royal baby.

During his first photocall, the baby was wrapped in a white lace shawl with a matching hat.

Only just under seven hours old, he was carried in his mother's arms, who was dressed in a vibrant red Jenny Packham dress with a white lace collar.

The baby could be seen moving his fingers as he was cradled by Kate.

Minutes after the brief photocall, the couple headed home to the sanctuary of Kensington Palace, with William emerging from the hospital carrying his son in a car seat, and holding Kate's hand.

The duke said they were "very happy" and "very delighted" and joked, holding up three fingers, that he now had "thrice the worry now".

He added: "We didn't keep you waiting too long this time."

Quizzed on whether they had decided on a name, the duke added: "You'll find out soon enough."

Siblings Prince George and Princess Charlotte had earlier visited their new sibling before being driven home to Kensington Palace.

Kensington Palace said earlier today: “Her Royal Highness The Duchess of Cambridge was safely delivered of a son at 1101hrs.

“The baby weighs 8lbs 7oz. The Duke of Cambridge was present for the birth.

“Her Royal Highness and her child are both doing well.

“Their Royal Highnesses would like to thank all staff at the hospital for the care and treatment they have received. They would also like to thank everyone for their warm wishes.”
