The TUC(B) was founded by the Socialist Party in November 1945, in an attempt to counter the influence of the communist-led All Burma Trade Union Congress.
At the May Day rally of 1950, TUC(B) demonstrators had carried large portraits of Karl Marx, Engels, Vladimir Lenin, Joseph Stalin and Mao Zedong.
In his speech at the rally, Lwin publicly declared that TUC(B) followed the 'communist party line' and said that the organisation should join the WFTU.
He harshly condemned the policy of the Burmese government of accepting British financial aid.
[3][4] Lwin's May Day speech had political repercussions, but did not result in any immediate disciplinary action from the Socialist Party or the AFPFL.
