A 1,800 to 1,900 strong mission was approved by The European Council on 14 December 2007. This was later increased to 2,000 personnel due to an increase in expected instability due to a lack of an agreement with Serbia.[17] It consists of police officers (including four anti-riot units[18]), prosecutors and judges – hence focusing on issues on the rule of law, including democratic standards. The size of the mission means Kosovo is home to the largest number of EU civil servants outside of Brussels.[19] Chief of the mission is French General Xavier Bout de Marnhac, who replaced Yves de Kermabon on 15 October 2010.
