 In 1921, the Union caused the dissolution of Parliament after it voted with Labor against the Nationalist government, over the issue of abolishing the state-run wheat-marketing system which had been introduced during World War I, and which benefited small farmers by keeping wheat prices high.At the 1921 state election, the Union increased its vote to 14% but the number of seats dropped to 12, and it continued to hold the balance of power.It would retain that position until 1952.
