In October 2010, Merkel told a meeting of younger members of her conservative Christian Democratic Union (CDU) party at Potsdam that attempts to build a multicultural society in Germany had "utterly failed", stating that: "The concept that we are now living side by side and are happy about it" does not work and "we feel attached to the Christian concept of mankind, that is what defines us. Anyone who doesn't accept that is in the wrong place here". She continued to say that immigrants should integrate and adopt Germany's culture and values. This has added to a growing debate within Germany on the levels of immigration, its effect on Germany and the degree to which Muslim immigrants have integrated into German society.
