A Formidable consensus of academic opinion exists on the question of the formation of Malaysia. In its most commonly stated form, this consensus is manifested in an explanation which specifies a date—27 May 1961—and sees Malaysia as the outcome of the attempt to solve the ‘Singapore Problem’. The movement towards Malaysia is, with dull regularity, dated from the Tunku's almost casual, certainly very vague, reference to the need for a ‘closer understanding’ between Singapore, British North Borneo (Sabah), Brunei, and Sarawak, and for ‘a plan whereby these territories can be brought closer together in a political and economic association’ which he made in the course of a speech to the Foreign Correspondents’ Association of South-east Asia on 27 May 1961. The Tunku's initiative arose, it is almost invariably argued, from the fear of future events in Singapore. Since the Republicwould in all probability be granted a separate independence by 1963,the British would no longer be in a position to control the island's internal security, defence and foreign relations. The Federation would be deprived of the Internal Security Council through which it had had (in conjunction with the British) direct control over Singapore's internal Malaya viewpoint if an amenable Singapore government could be guaranteed. By May 1961, however, the opposite appeared imminent. There were indications that the PAP was rapidly losing ground. In the Hong Lim by-election held in late April, its candidate was severely trounced. This, combined with the knowledge that no government had in the past managed to win more than one term of office, and full aware-ness of the seemingly perpetual leftward movement of Singapore politics, ness of the seemingly perpetual leftward movement of Singapore politics, created the impression in Kuala Lumpur that unless something was done, the Republic would become a second Cuba threatening the security of the Federation. The Tunku was convinced, so the argument goes, that the Federation had to ensure control over Singapore's internal security. A reversal of his previous stand on merger was, therefore, necessary. This explanation may be referred to as the security theory on the formation of Malaysia. It has a corollary: having decided that the incorporation of Singapore was necessary, the Tunku had to find a racial counter-balance to the island's Chinese population; the Borneo territories had to be included because it was essential that Singapore be territories had to be included because it was essential that Singapore be brought into the Federation of Malaya. Malaysia was thus the logicalsolution to the Singapore Problem. Among those who have propounded the security theory are Willard Hanna, Arnold Brackman, Gordon Means, George Me. T. Kahin, James Gould, Milton Osborne, Tan Koh Chiang, J. M. Gullick, Emily Sadka, Sir Richard Allen and Justus Van der Kroef.
