GMOs: the EU is discussing in favor of more national restrictions
The GMOs regulation is currently going to be revised in order to permit Member States to prohibit GMOs on their national territory.

Consequently, the Commission proposed amendments to the current rules and they are currently being discussed by the Parliament and the Council.
