The Chief Rabbi's full title is the "Chief Rabbi of the United Hebrew Congregations of the Commonwealth", previously "... of the British Empire". His title and position has historically, since 1758, been considered to be Britain's equivalent of the Archbishop of Canterbury for the Orthodox Jewish community.
