from amongst its members to represent minorities in Parliament. However, this was rejected as the Commission felt that it would be an inappropriate and retrogressive move in that unelected members should not be allowed to dilute the elected chamber. The second proposal, which was to have proportional representation, was also rejected on the grounds that it would intensify party politics along racial lines and eventually "perpetuate and accentuate racial differences". This would then make it increasingly difficult, if not impossible, to achieve a single homogeneous community out of the many races that form the population of the Republic. The third proposal was to have an upper house in Parliament composed of members elected or nominated to represent the racial, linguistic and religious minorities in Singapore. However, this was rejected as being backward-looking since politicians should attain a seat in Parliament through taking part in elections. Operation Number and boundaries of electoral divisions Apart from the requirement that there must be at least eight SMCs, the total number of SMCs and GRCs in Singapore and their boundaries are not fixed. The number of electoral divisions and their names and boundaries are specified by the Prime Minister from time to time by notification in the Government Gazette. Since 1954, a year ahead of the 1955 general election, an Electoral Boundaries Review Committee (EBRC) has been appointed to advise the executive on the number and geographical division of electoral divisions.

This is generally done just before a general election to review the boundaries of electoral divisions and recommend changes. In recent decades, the Committee has been chaired by the Cabinet Secretary and has had four other members who are senior public servants. In the EBRC appointed before the general election of 2006, these were the head of the Elections Department, the Chief Executive Officer of the Singapore Land Authority, the Deputy CEO of the Housing and Development Board and the Acting Chief Statistician. Since the Committee is only convened shortly before general elections, the preparatory work for boundary delimitation is done by its secretariat the Elections Department, which is a division of the Prime Minister's Office. The EBRC's terms of reference are issued by the Prime Minister, and are not embodied in legislation. In giving recommendations for
