The party was sitting on a powder keg of internal disagreement which could go off at any moment. The situation was triggered when the League of Communists of Yugoslavia invited a delegation from the Communist Party of Denmark to go to its 1958 congress. The CPSU and other communist parties had also accepted the invitation, but suddenly the CPSU decided to boycott the congress and pressured other communist parties not to send delegations either. Although Larsen's decision to go anyway was supported by the Danish executive committee, it was decided that Knud Jespersen and Børge Houmann were to go to Yugoslavia instead of Larsen.
