Left Party MP Cansin Köktürk was thrown out of a German parliament plenary chamber on Wednesday for wearing a t-shirt with the word “Palestine” printed on it, a move deemed a political statement by the parliamentary leadership.

Bundestag President Julia Klöckner intervened during the session, reminding MPs that political messages on clothing are not permitted in the chamber.

While the Bundestag does not have a detailed dress code, its rules require MPs and visitors to dress “in keeping with the prestige” of the institution. Enforcement of this standard is left to the discretion of the session chair.
