After the Open Flemish Liberals and Democrats (Open VLD) left the government on April 22, 2010, Prime Minister Yves Leterme offered his resignation to King Albert II. An election were then called for June 13, amid fears that coalition-building would once again be protracted. In Flanders, the New Flemish Alliance (N-VA) party won a plurality with 27.8% of votes, while the winning party in Wallonia was the Socialist Party.
