At the 2006 general election, Chiam See Tong was again re-elected as MP for Potong Pasir. However, the SDA did not win any other seats. Steve Chia lost his position as a non-constituency MP. Though Chia increased his share of the vote in Chua Chu Kang to 39.63%, this was lower than the 43.9% gained by the Workers' Party in Aljunied GRC. The role of "de facto" leader of the opposition in Parliament therefore passed from Chiam to the Workers' Party leader Low.
