 Koivisto countered that he had behaved properly and had let the parties themselves argue out a workable combination.One explanation for the unusual government was that animosity against the Centre Party (Kesk) leader, Paavo Väyrynen, was so common in both the SDP and the KOK that neither party was willing to form a government with him.Thus, Kesk was deprived of its traditional "hinge" role.
