Prince William attended his first official public engagement since news of his wife's pregnancy broke and joked that the name of her illness should be changed.

Former Centrepoint chairman Michael O'Higgins said of the Prince: "He said they shouldn't call it morning sickness as it's a day and all night sickness."
