The news will come on an easel. It's custom for news of royal births and deaths to be attached to the railings of Buckingham Palace. In this case, it will be displayed on an ornate easel in the forecourt of the palace. The Queen, senior members of the royal family, and the Middleton family - if they are not at the hospital - will be told about the birth first. Then a royal aide will hurry from the hospital to the palace under police escort with a bulletin. The foolscap-sized note, bearing the Buckingham Palace letterhead and signed by key medical staff, will be the nation's first chance to find out if it is a boy or a girl. After the note is displayed, an announcement will be posted on Twitter and Facebook, and the media will be informed.
