David and Samantha Cameron present baby Florence

David and Samantha Cameron appeared on the steps of No 10 this morning for a first photocall with their new daughter, Florence Rose Endellion. Florence will hopefully one day look back fondly on a morning when Her Majesty's press was almost exclusively focused on one subject – her nappies. "Changed any nappies?" one reporter yelled at the prime minister. "Hundreds," he eventually replied. "Has Nick Clegg changed any nappies yet?" asked another journalist (why, I don't know). "That's next," replied Cameron, equally bizarrely. Not to be outdone, the Press Association news agency reported: The appearance was delayed by more than 10 minutes and a Downing Street press officer said this was for "operational reasons". It was not clear if there was nappy changing involved. Poor Florence.
