The Malayan Union proposal provided that United Kingdom had full administrative powers over the Malay states except in areas pertaining spiritual and moral authority of the Malay rulers, which the Malays held high esteem over it. Communal tensions between the Malays and Chinese were high, and the prospect of granting citizenship to non-Malays was deemed unacceptable to the Malays. In particular, politicians in Johor were extremely unhappy with the willingness of Sultan Ibrahim to sign the treaties with Harold MacMichael, and voiced out that the Sultan had violated the terms in the Johor state constitution which explicitly forbade any foreign powers to assume legitimate control over the state.
