The Parliamentary elections in Belgium on  2010 saw the Flemish nationalist N-VA become the largest party in Flanders, and the Socialist Party PS the largest party in Wallonia. Until December 2011, Belgium was governed by Leterme's caretaker government awaiting the end of the deadlocked negotiations for formation of a new government. By 30 March 2011, this set a new world record for the elapsed time without an official government, previously held by war-torn Iraq. Finally, in December 2011 the Di Rupo Government led by Walloon socialist Prime Minister Elio Di Rupo was sworn in.
