Quisling left "Nordisk folkereisning i Norge" in May 1931 to serve as defence minister in the Agrarian government of Peder Kolstad, despite being neither an Agrarian nor a friend of Kolstad. He had been suggested to Kolstad for the post by Thorvald Aadahl, editor of the Agrarian newspaper "Nationen," who was in turn influenced by Prytz. The appointment came as a surprise to many in the Parliament of Norway. Quisling's first action in the post was to deal with the aftermath of the Battle of Menstad, an "extremely bitter" labour dispute, by sending in troops. After narrowly avoiding criticism by the left wing over his handling of the dispute, and the revelation of his earlier "militia" plans, Quisling turned his attention to the perceived threat posed by communists. He created a list of the Revolutionary Trade Union Opposition leadership, who had been the alleged agitators at Menstad; a number of them were eventually charged with subversion and violence against the police. Quisling's policies also resulted in the establishment of a permanent militia called the "Leidang" which, unlike the body he had previously planned, was to be counter-revolutionary. Despite the ready availability of junior officers in the reserve following defence cuts, only seven units were established in 1934, and funding restrictions meant that the enterprise included less than a thousand men before it faded away. Sometime during the period 1930–33, Quisling's first wife, Asja, received notice of the annulment of her marriage to him.
