On 6 June 1955, Adenauer, who had until then been Foreign Minister as well as Chancellor, appointed Heinrich von Brentano foreign minister and there was a reshuffling of responsibilities, but Hallstein retained the trust of Adenauer and continued to attend cabinet meetings. Herbert Blankenhorn, who until then been the head of the Political Department of the Foreign Office, became the German Permanent Representative to NATO in Paris; Wilhelm Grewe took over the Political Department under Hallstein and was made Hallstein's deputy.
