The Netherlands is one of the last countries in Europe not to have an elected mayor, instead he is appointed by the Crown. In order to change this the constitution has to be amended. A proposal to do this by former Minister of the Interior and Kingdom Relations Klaas de Vries (PvdA) in 2001, under the second Kok cabinet, was rejected in second reading by the Senate. This was because it would allow the controversial plans of De Graaf to be implemented. This would involve a mayor, directly elected by the city's population, who would have considerable power to take care of security and public order. The proposed election system would have preserved proportional representation but have done so with supplemental regional candidates.
