By royal charter dated 29 October 1900, the borough was granted the title City of Westminster. Westminster had originally been created a city and seat of the short-lived Diocese of Westminster in 1541. The diocese was suppressed in 1550, but the area was still known as a "city", although without official sanction.
Arms and motto
The arms of Westminster represent two monarchs, closely associated with the City. Edward the Confessor, who rebuilt the church of St Peter, and Henry VII, who added a chapel, within the Abbey. The portcullis and rose emblems are derived from the Tudor dynasty, from which Westminster first achieved its status; and they appear throughout many public and religious buildings in Westminster, and the portcullis was adopted by the House of Commons. The supporting lions are adopted from the Cecil family, who have had a long association with the borough. The arms were first granted in 1601. The motto Custodi Civitatem Domine, is translated as O Lord, watch over the City. The arms can still be seen on the Portland stone parapet of the former Westminster City Hall in St Martin's Place. It can also be seen on the entrance to the car park beneath 10 Spring Gardens and on Chelsea and Hammersmith Bridges.

The borough was divided into fourteen wards for elections: Charing Cross, Conduit, Covent Garden, Great Marlborough, Grosvenor, Hamlet of Knightsbridge, Knightsbridge St George's, Pall Mall, Regent, St Anne, St John, St Margaret, Strand and Victoria.
For elections to Parliament, the borough was divided into three constituencies:

Westminster
In 1918 the borough's representation was reduced to two seats:
Westminster Abbey
Westminster St George's
In 1950 the borough's representation was reduced to half a seat, when it was merged with the City of London:

Poor law
The parishes which made up the borough were within the St George's, Strand and Westminster unions. The unions were amalgamated in 1913 to form the City of Westminster Union. The parishes and unions were then abolished in 1922 and replaced with a single City of Westminster parish for poor law purposes. The parish continued to exist until 1965, but ceased to have any role in the administration of the poor law in 1930 when responsibility transferred to the London County Council.
