Fashion designer Stella McCartney has joined forces with PETA ahead of London Fashion Week, backing the charity's first ever anti-leather campaign.

A viral video exposé of the skins trade features McCartney saying 'As a Designer, I like to work with fabrics that don't bleed. Please join me in exploring the huge variety of fashionable shoes, belts, purses and wallets that aren't the product of a cow's violent death'. Marc Bouwer, Natalie Portman and Joan Jett are also supporting the initiative.
