Sir Harold MacMichael, representing the British Government, arrived in Kuala Lumpur on 11 October 1945. He came to Alor Setar after visiting the Sultans of Johor, Selangor, Pahang, and Perak and securing their signatures to a new treaty. In Kedah, MacMichael was told that the Ruler would consult his Council of State before discussing with him. With these consultations proceeded, rallies and processions in opposition to the treaty were held in every district and the center of Alor Setar. Tunku was one of the most popular speakers in Alor Setar, Sungai Petani, and Kulim, but he was not invited to take part in any of the discussions convened by his half-brother, Sultan Badlishah. After three days of negotiations, the Sultan followed the example of his brother rulers. The Sultan's surrender was vigorously criticised by the public and by Tunku. MacMichael flew back to London after securing all the signatures from the rulers for the new treaty. Then the British Prime Minister announced that the Malayan Union would come into effect on 1 April 1946.
