The first seat was taken by the "Federation of Frisian Municipal-interest Parties" and the second by Marten Bierman. Bierman was elected by preference votes. He formed a separate Independent Senate Fraction, a novelty in Dutch politics. Before no group had previously had representation in the Senate without also being present in the House of Representatives.
