It's a EU-wide law, part of the banning of all hate speech:
The EU Framework Convention on Racism and Xenophobia of 2008, in particular, requires Member States to prosecute hate speech in general, but singles out the denial of mass crimes for specific treatment, to the extent that they can be considered a form of hate speech(2). The crimes the denial of which would be prohibited under this piece of EU law would include genocides as well as crimes against humanity and war crimes.
