 This however increases the difficulty of the opposition parties being able to gain a seat.Until the general election in 2006, the PAP had always managed to return to power on nomination day, even before the elections commenced since the amendment to the Parliamentary Elections Act.The opposition accuses that the group representation constituency is an intentional hindrance, as between 1991 and 2001 did not manage to put forward enough qualified candidates to even contest the PAP's mandate.
