British supermarket Waitrose has launched a new Organic campaign with television presenter Ellie Harrison and Waitrose ambassador Alan Titchmarsh, who commented 'There's an immense amount of skill and passion involved in growing organic produce and I'm so pleased to play a part in helping people understand not only where our food comes from but also just how it’s grown'.

As part of the campaign Harrison will write a weekly column for the Waitrose Weekend newspaper, starting with the September 8 issue.
