If the vote swing continues to work to PAP's detriment in the next election, I think PAP will scrap First Pass the Post and introduce Proportional Representation by the 2021 elections. This is because if PAP gets into the same situation as the opposition currently, that is, having 40% of the votes but less than 10% of the representation in Parliament, this is a position from which PAP will find very difficult to recover from. If it implements Proportional Representation, it will at least provide some space for it to breathe and recover its strength within a few years should it not be able to win the majority of the votes.
If PAP manages to claw back their loss in the 2016 elections, then the urgency for Proportional Representation will not surface.
