Therefore, the Government felt that the best way to ensure minority representation in Parliament was to introduce the GRC scheme. In addition, it took the view that such a scheme would complement the introduction of town councils to manage public housing estates, as it would be economical for a town council to manage a group of three constituencies. Subsequently, in 1991, the Government said that GRCs also minimized the need to redraw the boundaries of constituencies which had grown too big for the MPs serving them, and, in 1996, GRCs were said to provide Community Development Councils with the critical mass of residents that they needed to be effective.
