London mayor Ken Livingstone has launched a strategy designed to improve London's food and reduce the environmental impact of the food industry.

The strategy has five themes - to improve Londoner's health through food, to reduce the negative environmental impacts of food, to support a vibrant food economy, to celebrate and promote London's food, and to develop London's food security.

Jenny Jones, chair of London Food, said: “This strategy is a radical vision of how London cam become a healthier, happier and greener city by encouraging the capital's food system to focus on good quality fresh, seasonal, local and fair trade produce.”
