of Finance, and Kyaw Nyein, Minister of Home Affairs, were not present at the meeting. Additionally, one of the assassins, Ba Nyunt, went to the office of Chamber of Deputies Speaker U Nu, who was not present because of a leave of absence due to minor illness. Ba Nyunt could not find U Nu. Later Ba Nyunt became the government witness in the trial process. Many Burmese believe that the British were somehow involved in the assassination plot; two British officers were also arrested at the time and one of them charged and convicted for supplying an agent of U Saw with arms and munitions. A large part of the stockpile, which was enough to equip a small army, was recovered from a lake next to U Saw's house in the immediate aftermath of the shooting. Soon after the assassinations, Major General Sir Hubert Rance, the last British Governor of Burma, appointed U Nu to head an interim administration and when Burma became independent on 4 January 1948, Nu became the first Prime Minister of Burma. 19 July was designated a public holiday known as Martyr's Day.
