The autonomous communities have wide legislative and executive autonomy, with their own parliaments and regional governments. The distribution of powers may be different for every community, as laid out in their Statutes of Autonomy, since devolution was intended to be asymmetrical. Only two communities—the Basque Country and Navarre—have full fiscal autonomy. Beyond fiscal autonomy, the ''nationalities''—Andalusia, the Basque Country, Catalonia, and Galicia—were devolved more powers than the rest of the communities, among them the ability of the regional president to dissolve the parliament and call for elections at any time. In addition, the Basque Country, Catalonia and Navarre have police corps of their own: Ertzaintza, Mossos d'Esquadra and the Policía Foral respectively. Other communities have more limited forces or none at all, like the ''Policía Autónoma Andaluza'' in Andalusia or the BESCAM in Madrid.
