In February 2010, the PvdA withdrew its support for the fourth cabinet Balkenende. The PvdA disagreed with prolonging the Dutch military involvement in Afghanistan. In the following 2010 general election, the conservative liberal VVD became the biggest party with 31 seats, followed closely by the PvdA with 30 seats. The right-wing PVV went from 9 to 24 seats, while the CDA lost half of their support and got 21 seats. The SP lost 10 of its 25 seats, and both D66 and GL got 10 seats. The ChristianUnion, the smallest coalition party, lost 1 of their 6 seats. Both the SGP and the PvdD kept their 2 seats. The following cabinet formation eventually resulted in the first Rutte cabinet, a minority government formed by VVD and CDA, supported in parliament by the PVV to gain a majority.
