Following the 2006 Dutch general election, held on November 22, a process of cabinet formation started, involving negotiations about which coalition partners to form a common programme of policy and to divide the posts in cabinet. On February 22, 2007 it resulted in the formation of the Fourth Balkenende cabinet.
The Netherlands has a large number of political parties across the political spectrum in the parliament, with no single party holding a majority. During the formation process, a coalition is formed, usually consisting of three parties. Dutch coalition negotiations are conventionally conducted in two stages:
The Dutch House of Representatives has 150 seats. In the 2006 elections the coalition partners of the cabinet in power before the fall of that cabinet earlier that year lost a total of 12 seats. Christian Democratic Appeal (CDA) lost three out of 44, the right-wing liberal People's Party for Freedom and Democracy (VVD) lost six out of 28 and the centre-left liberal D66 lost three of six. Nevertheless, the CDA remained the largest party in the parliament with 41 seats. The main opposition party, the social-democratic Labour Party (PvdA) lost nine of its 42 seats; getting 33 seats in the new parliament. The largest winner in seats was the Socialist Party (SP), which won 16 seats, increasing from nine to 25 seats. Two previously unrepresented parties were also successful; the far right-wing Party for Freedom (PVV) of former VVD MP Geert Wilders, winning nine seats, and the animal-rights Party for the Animals, winning two seats. The social, and orthodox Protestant, ChristianUnion (CU) doubled its seats from three to six. GreenLeft (GL) dropped from eight to seven seats, while the orthodox Reformed Political Reformed Party (SGP) remained stable with two seats.
