The royals are now parents on a baking hot day in London

Kate Middleton and Prince William‘s first baby has been born.

The royal couple, both 31, welcomed their son at the Lindo Wing of St Mary’s Hospital in Paddington, London, this afternoon at 4.24pm. He weighed 8lb 6oz and it was a natural delivery.

The birth comes over a week after Kate‘s rumoured due date, which was believed to be 13 July.

Prince William was present and is ‘delighted’ about the arrival of his first child.

Kate went into labour just before 6am this morning and William accompanied his wife as they travelled by car from Kensington Palace without any police escorts.

It was confirmed shortly after that the child was on its way.

‘Her Royal Highness The Duchess of Cambridge has been admitted this morning to St Mary’s Hospital, Paddington, London, in the early stages of labour,’ read a statement from the Palace.

‘The Duchess travelled by car from Kensington Palace to the Lindo Wing at St Mary’s Hospital with The Duke of Cambridge.’

Kate and William married in April 2011 and revealed that they were expecting last December.

Their son is now third in line to the throne.

Kate will stay in hospital overnight. The name will be announced ‘in due course’. Their little boy will be Prince of Cambridge.
