In 1925 the party was instrumental in the fall of the cabinet led by Hendrikus Colijn: each year the orthodox Protestant Reformed Political Party (SGP) proposed that the Dutch representation at the Vatican be removed. The Protestant SGP was fervently anti-Catholic. This proposal was always supported by the Protestant Christian Historical Union (CHU), which was part of the Catholic-Protestant cabinet, but nonetheless had an anti-Catholic history. For the Catholic leader Nolens, this Papal representation was of utmost importance. In 1925 the VDB had convinced the other opposition parties that this was their chance to let the government fall and create a progressive cabinet. The entire opposition voted with the SGP and CHU, and the cabinet fell. In the following 1925 elections the party gained two seats. The party leader, Marchant, attempted to form a progressive government with the Roman Catholic State Party (RKSP), the SDAP and the VDB. He failed, however, and a new Christian-democratic cabinet was formed.
