Celal Bayar, Adnan Menderes, M. Fuad Köprülü, and Refik Koraltan have presented the motion known as “Memorandum of the Four”, to the Parliament Group of Republican People’s Party (CHP), in which it contained wishes of full democracy for Turkey, and transition to a multi-party system. The motion was rejected, for reasons that it was going to cause a change of the existing legislations/laws, and the place to negotiate such proposals was not the Parliament Group of CHP but the Turkish Grand National Assembly (TBMM) itself. Thus Menderes and Köprülü who had signed the motion decided to carry out their fight in front of the public by using the media; they have started to voice their wishes of democracy through the articles they have wrote at the Vatan Newspaper which was described as an “opponent” by CHP, and with their statements. The articles of Menderes and Köprülü published by Vatan Newspaper have disturbed the CHP management. Reasoning that their behavior and attitudes during the Parliament meetings were not overlapping with the part principles, an inquiry was started on both of them by the CHP management. As a result of this inquiry the removal of Menderes and Köprülü from CHP was decided on. With this study Menderes and Köprülü’s removal process from Republican People’s Party will be evaluated in the light of archival documents, newspapers of the period and revised and compilation works
