Currently anyone can call food vegetarian if they vaguely think it is. Trading standards might be able to stop them if they willfully and persistently sell food as vegetarian that blatantly isn't and you report it.

But there is no legal definition of vegetarian and vegan – so it's all rather wooly and vague.

You can do your bit at the One Voice for Veggies stand at Womad 2005 to change this.

Vegetarian Charities, such as the Vegetarian Society are campaigning to get a legal definition of "vegetarian" and "vegan" in the UK.

They are working with the Food Standards Agency to develop guidelines on what these words mean. You can give feedback on these guidelines from where you sit: go to the FSA website to have your say.

In parallel to this there is an Early Day Motion in Parliament to make these terms legally defined. Ask your MP to give it their support.

Postcards will be available at the One Voice for Veggies stand at the Womad Festival 2005 which you can send to your MP then and there in the stand postbox, and we'll make sure it gets in the post.
