The Queen and Prince Philip are said to be ‘delighted’ at the news that The Duchess of Cambridge has given birth to a baby boy.
Prince Charles has also issued a statement saying he is ‘overjoyed’ to be a grandfather.
The future King was born at 4.24pm, at St Mary’s Hospital in London, weighing 8lbs 6oz.
The Prince of Wales said: “Both my wife and I are overjoyed at the arrival of my first grandchild.
“It is an incredibly special moment for William and Catherine and we are so thrilled for them on the birth of their baby boy.
“Grandparenthood is a unique moment in anyone’s life, as countless kind people have told me in recent months, so I am enormously proud and happy to be a grandfather for the first time and we are eagerly looking forward to seeing the baby in the near future.”
The Royal doctor was heard to say ‘wonderful baby, beautiful baby’ as he left the hospital earlier, and in the last few minutes, the Duke of Cambridge, who was present for the birth, said: “We couldn’t be happier.”
The baby boy, who’s name has yet to be revealed, will be third in line to the throne.
In a statement the palace said mother and baby were doing well, and will remain in hospital over night.
News of the birth came via email in a break with tradition. The official notification is now on display on the traditional, ornate easel at Buckingham Palace.
The Duchess had been in labour since early this morning and arrived at the hospital by car with no police guard.
