The surrender of the Japanese brought a military administration to Burma. The British administration sought to try Aung San and other members of the British Indian Army for treason and collaboration with the Japanese. Lord Mountbatten realised that a trial was an impossibility considering Aung San's popular appeal. After the war ended, the British Governor, Colonel Sir Reginald Dorman-Smith, returned. The restored government established a political programme that focused on the physical reconstruction of the country and delayed discussion of independence. The Anti-Fascist People's Freedom League (AFPFL) opposed the government leading to political instability in the country. A rift had also developed in the AFPFL between the communists and Aung San together with the socialists over strategy, which led to Than Tun being forced to resign as general secretary in July 1946 and the expulsion of the CPB from the AFPFL the following October.
