The Turkish President has warned that Turkey may review its relations with the "fascist and cruel" European Union as he urged voters to back him in a referendum that would vastly increase his power.
Recep Tayyip Erdogan's string of taunts at Europe, including accusing Germany of "Nazi" tactics, prompted a close political ally of Chancellor Angela Merkel to say yesterday that the Turkish President was "not welcome" in Germany.
"Enough is enough," said Volker Bouffier, vice-chairman of Merkel's Christian Democratic Union (CDU). "Mr Erdogan and his Government are not welcome in our country, and that must now be understood."
Bouffier said Germany could not be expected to "assemble thousands of police to protect" someone who had behaved so insultingly.
A Turkish expatriate group which has held rallies in Germany on behalf of Erdogan's party said in response it would not organise any more events with Turkish officials.
