The original proposal of the Speaker's Conference, which considered electoral reform before the 1918 legislation was prepared, was to combine all the English and Welsh universities except for Oxford and Cambridge into a three member constituency. However during consideration of the legislation it was agreed that London University alone should continue to return one member. The University of Wales was also given its own seat. The other universities, which were still to be combined, had their proposed representation reduced to two members. (Source: Pugh).
Combined English Universities was not a physical area. Its electorate consisted of the graduates of the Universities included in the seat.
