Prince William's first appearance since birth of baby Charlotte

Prince William has briefly left the Duchess of Cambridge with their newborn daughter Charlotte to support a cause close to his heart. The Prince attended a meeting of the United for Wildlife movement - a foundation he created with the Duchess, née Kate Middleton, and Prince Harry. It's the first time the father of two has been seen in public since he and Kate left Kensington Palace with their baby Princess and his big brother Prince George headed for their country retreat Anmer Hall.

Looking smart and alert at the event in Switzerland, William did an excellent job of hiding the fatigue he must be feeling with a small baby in the house. The taskforce aims to break the link between suppliers and consumers in the illegal wildlife trade, a subject he spoke about to President Obama and Hillary Clinton on his and Kate's tour of the US last year.

William has taken a combination of unpaid leave and paternity leave and is not expected at his other job as an air ambulance pilot until June 1.

The Cambriges have spent the last few weeks introducing Charlotte Elizabeth Diana to the rest of the family. Prince Charles, who previously admitted he wanted a little girl, had two visits with his granddaughter – one the day after her birth and another two days after that. He has been telling well-wishers that she is "very beautiful".

The Queen, who said she loved having another great-granddaughter, was also driven to Kensington Palace to see Charlotte.

Harry, who has just got back from Australia and New Zealand, has not yet had the pleasure of meeting the newest member of the family. Asked when he will see Charlotte, the royal said: "We'll wait and see. That still hasn't happened yet. I only got back yesterday afternoon. Time will tell when I have a chance."

The Prince did, however, get sent a picture by William before everyone else in the world had seen her on the steps of the Lindo Wing of St Mary's Hospital, where she was born at 08:34am on 2 May. Harry said it was "very nice" to receive a picture so early on.
