A BBC reporter broke the news that the Duke and Duchess of Cambridge are expecting a baby to Labour leader Ed Miliband, who was busy debating the Leveson Report in the House of Commons.

Norman Smith explains how a text message sent to his advisors asking for their response led to them stating Mr Miliband "will tweet soon".

Ed Miliband subsequently said on Twitter: "Fantastic news for Kate, William and the country. A royal baby is something the whole nation will celebrate."
