Government

Metro Manila does not have collective political power. The highest political division are the sixteen cities and the Municipality of Pateros which have political power independent from each other. Each is governed by a mayor who belongs to the Metro Manila Mayor's League, which is part of the Metropolitan Manila Development Authority (MMDA).

Unlike other regions which are divided into provinces, Metro Manila or the National Capital Region (NCR) is divided into four nonfunctioning districts, which are grouped according to geographical basis in reference to the Pasig River. These districts were created in 1976 but have no local government and no congressional representation, in contrast to that of the provinces. These districts are used mostly for fiscal and statistical purposes.

The cities and municipalities within the NCR are grouped into the four districts as follows:

1. The Capital District: Manila
2. Eastern Manila District: Mandaluyong City, Marikina City, Pasig City, Quezon City, and San Juan City
3. CAMANAVA District: Caloocan City, Malabon City, Navotas City, and Valenzuela City
4. Southern Manila District: Las Piñas City, Makati City, Muntinlupa City, Parañaque City, Pasay City, Pateros, and Taguig City

The cities and Pateros are independent from each other politically but several services such as traffic and flood control are handled collectively by the MMDA under the Office of the President.

Representation to the two houses of the Congress of the Philippines is as follows:
* For the Senate, polling is done at-large, nationwide.
* For the House of Representatives, each city except for Malabon and Navotas has at least one representative; Malabon and Navotas has one representative (until 2010, when they will have separate seats), while Pateros' representation is included with the first Sangguniang Panlungsod district of Taguig.

Metro Manila is also a judicial region; as such, all regional trial court judges can be stationed anywhere within the region.
