The alliance with the Nationalists eventually led to a split in the Labour Party when Hertzog dropped Labour MP Walter Madeley from the cabinet in 1928 due to his support for the multiracial Industrial and Commercial Workers' Union. Creswell and his supporters remained in government and became known as the "Creswell Labour" faction while Madeley and other Labour MPs joined the Opposition and became known as "National Council Labour" due to their being supported by the Labour Party's national council. In 1933, the Creswell Labour faction dissolved with its members joining the Hertzog's party.
