Konstantinos Karamanlis

In Germany, Merten was eventually acquitted from all charges due to "lack of evidence." On 28 September 1960 German newspapers Hamburger Echo and Der Spiegel published excerpts of Merten's deposition to the German authorities where Merten claimed that Karamanlis, the then Minister for the Interior Takos Makris and his wife Doxoula (whom he described as Karamanlis's niece) along with then Deputy Minister of Defense George Themelis were informers during the Nazi occupation of Greece. Merten alleged that Karamanlis and Makris were rewarded for their services with a business in Thessaloniki which belonged to a Greek Jew sent to the Auschwitz concentration camp. He also alleged that he had pressured Karamanlis and Makris to grant amnesty and release him from prison.
