Veganism is a protected belief under the European Convention on Human Rights, as mentioned [here in The (UK) Vegan Society's key facts page](https://www.vegansociety.com/about-us/key-facts) - see also [this recent update](https://www.vegansociety.com/whats-new/news/written-judgement-concluding-veganism-protected-belief).

>Veganism is protected as a human right under [Article 9](https://en.wikipedia.org/wiki/Article_9_of_the_European_Convention_on_Human_Rights) of the European Convention for the Protection of Human Rights. 

This does mean, I believe, that prisons, hospitals and schools, for example, need to provide vegan options if they are requested.

[Here is the treaty](http://www.coe.int/en/web/conventions/full-list/-/conventions/treaty/005) and [here is the information](http://www.coe.int/en/web/conventions/full-list/-/conventions/treaty/005/signatures?p_auth=sRzd10TG) on when each state signed and ratified it. It applies across the EU, in my understanding.

I suppose we are waiting for an update as to its future applicability in the UK :(
