Once the king had declared the German commission unlawful, it became clear that he would never be won over. An impatient Hitler appointed a German, Josef Terboven, as the new Norwegian "Reichskommissar," or Governor-General, on 24 April, reporting directly to him. Despite Hitler's assurances, Terboven wanted to make sure that there would be no room in the government for the "Nasjonal Samling" nor its leader Quisling, with whom he did not get along. Terboven eventually accepted a certain "Nasjonal Samling" presence in the government during June, but remained unconvinced about Quisling. As a result, on 25 June, Terboven forced Quisling to step down as leader of the "Nasjonal Samling" and take a temporary leave of absence in Germany. Quisling remained there until 20 August, while Rosenberg and Admiral Erich Raeder, whom he had met on his earlier visit to Berlin, negotiated on his behalf. In the end, Quisling returned "in triumph," having won Hitler over in a meeting on 16 August. The "Reichskommissar" would now have to accommodate Quisling as leader of the government, then allow him to rebuild the "Nasjonal Samling" and bring more of his men into the cabinet. Terboven complied and addressed the Norwegian people in a radio broadcast in which he asserted that the "Nasjonal Samling" would be the only political party allowed.
