The local authority is the Westminster City Council. The council provides a wide array of services including urban planning, social care, waste management, housing, and library services. For decades, the council was a stronghold for the Conservative Party, but in a historic shift during the 2022 local elections, the Labor Party won control for the first time since the borough's creation in 1965.
Westminster operates on a leader-and-cabinet model, headed by the Leader of the Council. The borough is divided into numerous electoral wards, each represented by elected councillors. The ceremonial figurehead of the council is the Lord Mayor of Westminster, a title reflecting the borough's historic city status.
At the national level, the City of Westminster is represented in the House of Commons by Members of Parliament. It is currently split into two main parliamentary constituencies: the Cities of London and Westminster, and Queen's Park and Maida Vale (following recent boundary changes).
