Greater London boroughs north of the Thames and west of Waltham Forest and Newham, plus the City of London, the districts of Staines and Sunbury-on-Thames, and the county of Hertfordshire.
The diocese essentially covers the same region as the Church of England Diocese of London as it was before the English Reformation until 1850, adopting—like all other dioceses across England (created that year)[5]—an alternative name (originally because of the Ecclesiastical Titles Act 1851) but based on the centuries-old divisions of the country.[6] The diocese effectively survived the period of Catholic oppression in English history as a missionary territory established by canons accepted by Rome in 1622 as the Apostolic Vicariate of England which was in public law pronounced in England and Wales illegal as counter to the established church.
The mostly clandestine apostolic vicariate covering the country was divided so that the Apostolic Vicariate of London District formed on 30 January 1688 coinciding with a degree of freedoms. By decree of Pope Pius IX(Universalis Ecclesiae), this entity gained its elevation to the rank of a metropolitan diocese (instead of archdiocese) on 29 September 1850.
On 3 April 2009, it was announced that the Archbishop of Birmingham, the Most Reverend Vincent Nichols, would become the 11th Archbishop of Westminster.[7]Cormac Murphy-O'Connor, who was installed as tenth Archbishop of Westminster on 22 March 2000 and was elevated to the rank of cardinal-priest of the title of Santa Maria Sopra Minerva by Pope John Paul II on 21 February 2001, became archbishop emeritus. Cardinal Murphy-O'Connor had announced on 9 July 2007 that, in accordance with the age limit of 75 years prescribed for bishops in the 1983 Code of Canon Law, he had submitted his resignation to Pope Benedict XVI, but that the Pope had asked him to continue in his pastoral ministry as archbishop beyond the age limit until further provision was made, as occurred in 2009.
The archbishop is usually assisted by four auxiliary bishops, each with specific areas of responsibility within the administration of the diocese. One of the auxiliary bishops serves as chancellor and moderator of the metropolitan curia; one as vicar for the clergy; one for pastoral affairs; and one for education and formation.
John Larkin, appointed Coadjutor Bishop of Kingston, Ontario, Canada in 1832 and Bishop of Toronto, Ontario, Canada in 1849; neither took effect; became a Jesuit in 1840
Liturgy in the diocese is primarily based around the ordinary form of the Roman Rite, promulgated by Pope Paul VI, now in its third edition. However, as might be expected from a city as cosmopolitan as London, there is a great diversity in the liturgy as celebrated by Catholics. The Latin Mass Society celebrates the liturgy according to the extraordinary form of the Roman Rite. The Ukrainian Greek Catholics have a strong presence in the diocese with their own cathedral in Binney Street close to Bond Street. There is a Lebanese Maronite community based at Our Lady of Sorrows Catholic Church in Cirencester Street in West London; a Melkite community in Pimlico, at St Barnabas' Church of England church; an Ethiopian Catholic church, Our Lady Queen of Heaven, in Queensway West London; an Eritrean Catholic Church, St Aidan of Lindisfarne, in East Acton; a Chaldean Catholic church, St Anne's, in Laxton Place; and a Belarusian Catholic church in Holden Avenue in North London. There are also a large number of Masses for the expatriate Polish community; as well as dedicated French, German, Italian, Portuguese and Spanish language churches. There are also ethnic chaplaincies serving Catholics from Africa, Albania, Brazil, the Caribbean, China, Croatia, the Philippines, India, Hungary, Ireland, Korea, Latin America, Lithuania, Malta, Portugal, Romania, Slovakia, Czechia, Slovenia, Sri Lanka, Traveller, Gypsy and Roma communities, and Vietnam.[8]

The diocese is involved in both the independent and state school sectors. Some 159 state and 10 independent primary schools are in the diocese along with 42 state and 4 independent secondary schools. There are also a further five independent primary / secondary and special schools including the Choristers school attached to the cathedral.
Music in the diocese is as diverse as the communities represented in it, but the all-male cathedral choir is reputedly one of the best in the country[9][10] and sings at all chief Masses in the cathedral as well as the daily divine offices. There are several choirs that specialise in Gregorian Chant and a Charismatic group centred on the diocesan seminary at Allen Hall.
^"As ordinary of the Diocese of Westminster his jurisdiction extends over much the same area as that of the Bishop of London. As chief metropolitan, he occupies a position similar to that of the Archbishop of Canterbury, Primate of All England" (Herbermann, Charles, ed. (1913). "Archdiocese of Westminster" . Catholic Encyclopedia. New York: Robert Appleton Company.). (At the bottom of the article, the first source listed is "Archives of the Diocese of Westminster.) Retrieved 2017-06-14. "By the grant in the Apostolic Constitution of 'certain new distinctions of preeminence', for the preservation of unity in government and policy, to the archbishop of Westminster for the time being, comprised under the following three heads: He will be permanent chairman of the meetings of the Bishops of all England and Wales, and for this reason it will be for him to summon these meetings and to preside over them, according to the rules in force in Italy and elsewhere. (2) He will take rank above the other two Archbishops, and will throughout all England and Wales enjoy the privilege of wearing the Pallium, of occupying the throne, and of having the cross borne before him. (3) Lastly, in all dealings with the Supreme Civil Authority, he will in his person represent the entire Episcopate of England and Wales. Always, however, he is to take the opinion of all the Bishops, and to be guided by the votes of the major part of them'. Thus, though the Archbishop of Westminster was vested with more powers and privileges than primates usually enjoy, unity of action has been safeguarded" (Herbermann, Charles, ed. (1913). "Reorganization of the English Hierarchy" . Catholic Encyclopedia. New York: Robert Appleton Company.).
