After the return of the British who had established a military administration, the
Anti-Fascist Organisation (AFO), formed in August 1944, was transformed into a united front, comprising the BNA, the Communists and the Socialists, and renamed the
Anti-Fascist People's Freedom League (AFPFL). The Burma National Army was renamed the Patriotic Burmese Forces (PBF), and then gradually disarmed by the British as the Japanese were driven out of various parts of the country. The Patriotic Burmese Forces, while disbanded, were offered positions in the Burma Army under British command according to the
Kandy conference agreement with
Lord Mountbatten in
Ceylon in September
1945. Some of the veterans had been formed into the
Pyithu yèbaw tat (People's Volunteer Organisation or PVO) under Aung San, a paramilitary force in uniform and openly drilling in public, which may have overcome the initial reluctance on the part of the British authorities. Aung San was offered the rank of Deputy
Inspector General of the Burma Army, but he declined it in favor of becoming a civilian political leader.
In January
1946, Aung San became the President of the AFPFL following the return of civil government to Burma the previous October. In September, he was appointed Deputy Chairman of the Executive Council of Burma by the new British Governor Sir
Hubert Rance, and was made responsible for defence and external affairs. Rance and Mountbatten took a very different view from the former British Governor Sir
Reginald Dorman-Smith, and also
Winston Churchill who had called Aung San a 'traitor rebel leader'. A rift had already developed inside the AFPFL between the Communists and Aung San leading the nationalists and Socialists, which came to a head when Aung San and others accepted seats on the Executive Council, culminating in the expulsion of
Thakin Than Tun and the CPB from the AFPFL.
Aung San was to all intents and purposes
Prime Minister, although he was still subject to a British
veto. On
January 27 1947, Aung San and the British Prime Minister
Clement Attlee signed an agreement in
London guaranteeing Burma's independence within a year - he had been responsible for its negotiation. During the stopover in
Delhi at a press conference, he stated that the Burmese wanted 'complete independence' not dominion status and that they had 'no inhibitions of any kind' about 'contemplating a violent or non-violent struggle or both' in order to achieve this, and concluded that he hoped for the best but he was prepared for the worst. He is also believed to have been responsible, in part, for the persecution of the
Karen people, based on their loyalty to the British and having fought the Japanese and the BIA. Dorman-Smith had in fact rejected a request for an AFPFL delegation to visit London and tried to bring Aung San to trial for his role in the execution of a village headman during the war.
Two weeks later, on
February 12 1947, Aung San signed an agreement at the
Panglong Conference, with leaders from other national groups, expressing solidarity and support for a united Burma. In April, the AFPFL won 196 of 202 seats in the election for a constituent assembly. In July, Aung San convened a series of conferences at the Sorrenta Villa in Rangoon to discuss the rehabilitation of Burma.
