British Prime Minister David Cameron's wife Samantha has given birth to a baby girl, his office said.

"Both the baby -- who was born weighing 6lbs 1oz (2.7 kg) -- and Mrs Cameron are doing very well," a statement from the prime minister's Downing Street office said.

The last British prime minister to have a baby in office was former Labor¹ leader Tony Blair, whose wife Cherie gave birth to their fourth child, Leo, in May 2000. Leo Blair was the first child born to a serving British prime minister for 150 years.

The Camerons' baby, who has not yet been named, was born at midday Tuesday, a few weeks earlier than expected, while the couple were on holiday in Cornwall, southwest England.
