A 17-year-old entrepreneur has succeeded in getting his chocolate bars into Sainsbury's following success in Selfridges.

Louis Barnett, director of Chokolit, which he set up in 2005, specialises in ethical and palm oil-free chocolate products. His three-line range of 75g Biting Back Bars will hit Sainsbury's this month with 10p from each bar going to animal conservation projects worldwide.

The dark chocolate Orangutan Biting Back bar, milk chocolate Amur Tiger & Leopard Biting Back bar and white chocolate Tiger Biting Back bar will all retail for £1.99.
