In 2010, Rutte won the elections with his party. He did not gain a majority in parliament, he won 31 out of 150 seats. Before he could form his government, there were four weeks of negotiations with the Christian-democratic CDA and the right-wing PVV of Geert Wilders. Wilders was not in the government, but he was supporting the government on several issues. These issues were discussed in those four weeks. When he was sworn in on 14 October 2010, he became the first liberal Prime Minister in the Netherlands in 92 years.
