Over the seven years I have been chair of the Commission I have met a wide variety of people from NGOs and also most of the corporate sponsors to talk about issues related to the sustainability of the Games and its legacy.

The combined turnover of Kraft (Cadbury), McDonald's and Coke is £116 billion - which, funnily enough is equivalent to the entire sport industry worldwide. We accept that the product they provide is not good for you if consumed in excess. But if they don't use sport then they will spend their advertising dollars elsewhere and I would prefer them to be driving their money into sport.

Well there is no beating around the bush now I have started with that headline. How did we end up here?
