A limited form of opposition to "ketuanan Melayu" and UMNO during this period came from the All-Malaya Council of Joint Action (AMCJA) which initially opposed the Malayan Union because of its exclusion of Singapore, lack of universal suffrage, and restricted civil liberties. The AMCJA, which was an amalgamation of several smaller organisations and trade unions, claimed to be the only organisation sufficiently representative of Malaya to be able to negotiate with the British, and demanded a place at the bargaining table with the British for negotiations on the Federation's formation. Later, the MNP (which had not been deregistered yet) and several other Malay organisations left the UMNO fold and formed the Pusat Tenaga Raayat (PUTERA). Although the MNP had insisted on "ketuanan Melayu" as a "National Birthright" of the Malays, PUTERA forged a compromise with the AMCJA to work together towards, among other things, "Equal political rights for all who regarded Malaya as their real home and as the object of their loyalty." Even so, not all was smooth sailing; the original name of the AMCJA had used the phrase "All-Malayan", but this was altered after PUTERA objected, as the Malays perceived the term "Malayan" to specifically exclude the Malays. After the British refused to appoint a Malayan to head the Consultative Committee which would canvass the views of Malayans on the existing proposals for the Federation, the PUTERA-AMCJA coalition pulled out of negotiations with the British. Nevertheless, they continued to influence Malayan politics right until the formation of the Federation in 1948, when they launched a hartal (boycott) to protest perceived defects in the Federation proposal. The hartal is estimated to have cost the Malayan economy £4 million. After the Federation was formed over their objections, the coalition disbanded.
