The United Synagogue (US) is the largest umbrella body for Orthodox Judaism in Britain. It is structured as a charity which serves the British Jewish community in the broadest possible way. One of the largest charities in the British Jewish community, it provides much of the infrastructure for the British Jewish community and supports 56 centrist Orthodox Jewish member synagogues. With more than 36,000 members, it is also the largest synagogue body in Europe. The work of the charity includes KLBD, its kashrut (kosher food) department, nurseries, marriages, the United Synagogue Burial Society, Tribe programmes and summer camps for young people, its Chesed team supporting vulnerable people and the highly-respected London Beth Din. The charity also supports the work of the Office of the Chief Rabbi. The spiritual head of the United Synagogue is Chief Rabbi Sir Ephraim Mirvis KBE, the Chief Rabbi of the United Hebrew Congregations of the Commonwealth—a title that bears some formal recognition by the Crown.
