Today, the EU has shown that we can deliver.
The Council reached a general approach on the safe third country concept and the first EU safe country of origin list. These are all measures that will help process claims more effectively and reduce pressure on asylum systems.

Statt Kompromisse mit der Mitte zu suchen, peitscht sie ihre Maximalposition mit extrem Rechten durch‼️ Das schwächt das EU-Entwaldungsgesetz, bestraft vorbildliche Unternehmen & gefährdet bis zu 150.000 Hektar Wald.
