U Nu
By mid-1958 Ba Swe had fallen out with his senior colleague U Nu. The AFPFL split into two factions, and Ba Swe together with his colleague Kyaw Nyein and thirteen other ministers resigned from the government on 4 June 1958 and tabled a motion of no-confidence against U Nu in Parliament. On 8 June 1958 the no-confidence motion was put to a vote in Parliament but the government of U Nu survived the motion by a mere 8 votes because the leftist NUF voted with the government.
