Former Beatle Sir Paul McCartney, his fiancΘe, Ms Heather Mills, and daughter, the fashion designer Stella McCartney, made an anti-war statement yesterday when, to the music of John Lennon's Give Peace a Chance, they posed for photographers at the Paris Fashion Show catwalk making peace signs, writes Francesca Fearon. The incident took place at the finale of Ms McCartney's first own-label collection show, backed by the Gucci Group.
