As the national capital, Lusaka is the seat of the legislative, executive, and judicial branches of government, epitomised by the presence of the National Assembly (parliament), the State House (office of the President), and the High Court. The Parliament is situated at the Parliament complex, which features a 15-story building. The city is also the capital of Lusaka Province, the smallest and most populous of the country's ten provinces, and forms an administrative district run by Lusaka City Council. The city council is headed by the Mayor of Lusaka, with Miles Sampa the incumbent as of 2021.
