An overjoyed Duke and Duchess of Cambridge are the proud parents of a 'beautiful' baby boy, as Britain celebrates the birth of a future king.
The couple's son was delivered at 4.24pm yesterday in the private Lindo Wing of St Mary's Hospital in Paddington weighing a bouncing 8lbs 6oz and with his proud father looking on.
The as yet unnamed baby will be given the title His Royal Highness and be known as Prince (Name) of Cambridge, after a decree by the Queen earlier this year.
The new prince is 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.
Recent legislation allowing female heirs to automatically accede to the throne if they are first born will clearly not affect the Cambridge's son, but will have a bearing on any of his children.

News of the royal birth - which came after an 11 hour labour - was not made public by Kensington Palace until 8.29pm last night, four hours after the baby was born.
Sources said the couple 'just wanted to spend a little time together to bond as a family' and inform members of both families privately before the news was disseminated to the world. William made those calls personally.
The Queen, who arrived back at Buckingham Palace just after 3pm yesterday, declared herself 'delighted' - as did all.
Kate, 31, will remain in hospital overnight with her baby - her husband is also, unusually, expected to stay with her - but may be discharged as early as tomorrow after being assessed by doctors first thing.
Surprisingly, no family visitors were expected last night - not even the Middleton family - as the couple want to spend some time alone together, sources told the Mail.
