Media across much of the world have been swept along by royal baby fever, particularly in North America, where news outlets have been dwelling on what the future holds for the prince who was born at St Mary's Hospital in Paddington, west London, on Monday.

Here Newsnight's Gavin Esler talks to Michael Wolff, contributing editor of Vanity Fair magazine, Dr Lucy Worsley, chief curator of Historic Royal Palaces, Peter Conradi, author of The Great Survivors and Joan Smith, a columnist for the Independent on Sunday, about why people overseas are so interested in the British royal family.
