David Cameron's wife Samantha has left hospital with her new baby.
Mrs Cameron had been at the Royal Cornwall Hospital in Truro since giving birth to daughter Florence Rose Endellion by Caesarean section on Tuesday.
She was driven from the rear of the hospital's maternity unit in a black people carrier without waiting photographers, television cameras and reporters catching a glimpse of the new baby.
A hospital spokesman confirmed that Mrs Cameron had been discharged after a third night at the Royal Cornwall.
David Cameron's wife Samantha is to spend a third night in hospital following the birth of the couple's new baby.
The baby was due in September but took the family by surprise while they were on holiday in Cornwall.
The baby has been named Florence Rose Endellion. St Endellion is a village on the north Cornish coast, close to where they were staying.
The couple received congratulatory messages from the Queen, the Prince of Wales, Gordon and Sarah Brown and French President Nicolas Sarkozy.
Their elder children, six-year-old Nancy and four-year-old Arthur Elwen, have visited their sister, who was born weighing 6lb 1oz.
Deputy Prime Minister Nick Clegg said Mr Cameron had not yet decided when he would be returning to his desk in Downing Street.
The Prime Minister had been expected to be back at No 10 next week following his two week family holiday, but Mr Clegg said he would now want to take some paternity leave.
