ABSTRACT
In view of Vilhelm Evangs identification with the Left in Norwegian politics, particularly because of his membership of the communist Mot Dag movement in the 1930s, it would not have been surprising if the new government had sought a change in the important post of chief of the NIS. The final breach in relations between Evang and Bryhn, and between the NIS and the Security Police, came in the sensational and much-debated Lygren Affair. It was known that Evang and Bryhn did not work well together, and as the Mellbye Commission got to work there soon appeared a broad consensus that both had to go. There was also a fair amount of accumulated dissatisfaction with Evangs management and leadership style both within the intelligence staff and in the military establishment. Evang resigned on reaching retirement age in 1974. He died in 1983 at the age of seventy-four.
