economist at lancaster university welcome to you all. coming to you first demonstrations today and tomorrow planned against mr erdogan and his visit does he understand why do you think. i think he understands why that there are people who are very unhappy with his offer of terrorism these are typically the people who we put in prison in turkey but they're free here in germany as it should be and they're free to demonstrate so i think he gets a glimpse of what an open society looks like and what opposition in an open society looks like sin and bacon in istanbul how easy or difficult is it for mrs merkel to on the one hand roll out the red carpet and on the other hand come up with some uncomfortable truths because it's not an easy sell for her well in international relations you should sometimes sacrifice your ego to sue for for for the better cause you know for the sake of your country so germany at one to hand needs turkey to assure european security. but also. has the pressure of the public opinion in germany to assert that president don's. policies may sometimes drift through. au
