Government Administration Bucharest has a unique status in Romanian administration, since it is the only municipal area that is not part of a county. Its population, however, is larger than that of any other Romanian county, hence the power of the Bucharest General Municipality (Primăria Generală), which is the capital's local government body, is the same as any other Romanian county council. The Municipality of Bucharest, along with the surrounding Ilfov County, is part of the București – Ilfov development region project, which is equivalent to NUTS-II regions in the European Union and is used both by the EU and the Romanian government for statistical analysis, and to co-ordinate regional development projects and manage funds from the EU. The Bucharest-Ilfov development region is not, however, an administrative entity yet. The city government is headed by a general mayor (Primar General). Since 29 October 2020 onwards, the general mayor of Bucharest is Nicușor Dan, currently an independent politician previously backed by the PNL-USR PLUS centre-right alliance at the 2020 Romanian local elections. Decisions are approved and discussed by the capital's General Council (Consiliu General) made up of 55 elected councilors. Furthermore, the city is divided into six administrative sectors (sectoare), each of which has its own 27-seat sectoral council, town hall, and mayor. The powers of the local government over a certain area are, therefore, shared both by the Bucharest municipality and the local sectoral councils with little or no overlapping of authority. The general rule is that the main capital municipality is responsible for citywide utilities such as the water and sewage system, the overall transport system, and the main boulevards, while sectoral town halls manage the contact between individuals and the local government, secondary streets and parks maintenance, schools administration, and cleaning services. The six sectors are numbered from one to six and are disposed radially so that each one has under its administration a certain area of the city centre. They are numbered clockwise
