У Ну
Ba Swe assumed the premiership in the aftermath of the parliamentary elections held in early 1956. Though the ruling Anti-Fascist People's Freedom League (AFPFL – "hpa hsa pa la") was returned the leftist coalition of parties known as the National United Front (NUF – "pa ma nya ta") won 37% of the vote. The number of NUF seats in Parliament was increased. However, on account of the 'first-past-the-post' electoral system, the NUF's representation in the Burmese Parliament was not reflected in the seats that it obtained. Still, the 1956 election results came as a shock to the AFPFL government. U Nu, the Prime Minister at the time, temporarily relinquished his office in order to devote full-time to reorganizing and strengthening the AFPFL. Ba Swe, as a deputy of U Nu in the AFPFL and leader of the Socialist Party, took over the job from U Nu. After less than nine months U Nu resumed office as Prime Minister on 28 February 1957.
