The proposal was announced on 10 October 1945 by George Hall, Secretary of State for the Colonies. Sir Harold MacMichael was empowered to sign revised treaties with the Malay Sultan's to enable the Union to proceed. MacMichael made several visits to the Malay rulers, beginning with Sultan Ibrahim of Johor in October 1945. The Sultan quickly consented to MacMichael's proposal scheme, which was motivated by his strong desire to visit England at the end of the year. MacMichael paid further visits to other Malay rulers over the proposal, and sought their consent over the proposal scheme. Many Malay rulers expressed strong reluctance in signing the treaties with MacMichael, partly because they feared losing their royal status and the prospect of their states falling into Thai political influence.
