The world has seen the royal baby for the first time as the future king left hospital with his ecstatic parents this evening, who revealed they had not yet chosen him a name.
Prince William and Kate waved and smiled broadly to the waiting cameras as they held their prince on the steps of the private Lindo Wing at St Mary's Hospital in London, 26 hours after he was delivered, weighing 8lbs 6oz.
Speaking for the first time since giving birth, an obviously moved Duchess of Cambridge said: 'It's been very emotional. Any parent will know what this feeling is like.'
As they left St Mary's carefully cradling their precious child, the Duke of Cambridge followed the steps his parents Charles and Diana took with him 31 years ago, when he was born there on June 21, 1982.
'He's a big boy, quite heavy. We're still working on a name,' he told reporters, adding: 'Well he has a good pair of lungs on him, that's for sure.'
Confirming that the prince was overdue, William said: ‘I will remind him of his tardiness when he is older.’
With a huge smile he then added: ‘He’s got her looks thankfully’ to which the Duchess responded ‘No, no, no I’m not sure about that.’
The Duchess wore a lilac purple dress, with her long hair falling in waves around her face. The new father wore a blue open neck shirt rolled up to his sleeves with black trousers.
The couple then returned to the hospital as William held his son, swaddled in a blanket, before bringing him out again in his car seat
William then visibly breathed a sigh of relief when he successfully installed his baby on the back seat with his wife, before driving them home to Kensington Palace cheered on by a huge crowd.
