Britain's first union across denominational lines took place in 1972 when the Congregational Church in England and Wales merged with the Presbyterian Church of England. Negotiations had gone on since 1945. Less than 20 percent of the Congregationalists had exercised their right to vote and, on the other hand, some Congregationalists planned to opt out and continue as a Congregational association. In the much smaller Presbyterian Church, the two congregations in the Channel Islands declined to enter the new body and have been accepted into the Church of Scotland. The URC is divided into twelve provinces, each with a moderator, and sixty-one districts. Ministers number 1,100, and estimated membership is 200,000. Overseas work is carried out through the Council for World Mission (Congregational and Reformed).
