It is impossible to swear an oath to the German Basic Law without realizing that our constitution is among the most liberal constitutions in the world. As the head of government in such a country, I would stand up to all those who call into question this free, open and tolerant model of society.

We need a common European tax policy that closes these tax loopholes. We need a common European social policy that prevents social dumping. We need an effective securing of our external borders and a smart way of fighting terrorism. Acting as a state within a national framework is no longer enough.
