And then there were four.
Dr Koh Poh Koon (People's Action Party), Lee Li Lian (Workers' Party), Desmond Lim (Singapore Democratic Alliance) and Kenneth Jeyaretnam (Reform Party) will contest the Punggol East by-election after successfully filing their nominations on Wednesday morning.
The four-way contest will be Singapore's first since the 1997 elections.
Two independent candidates Zeng Guoyan and Ooi Boon Ewe added to the spice and colour at the nomination centre at North Vista Secondary School but both ultimately failed to file their papers.
Zeng arrived on a motorcycle shortly after 11am, dressed in Middle Eastern garb. He eventually abstained from filing his papers, saying "there is no justice in the system and the law is blind", a reference to the fact that he was not qualified to contest because of a prior offence in 2008.
Ooi, meanwhile, said his nominations papers "were missing" when he arrived at the centre and promptly left.
As nomination hour closed and the four candidates were officially announced as candidates for Punggol East, each took to the stage and addressed their supporters.
PAP's Koh took turns to address his supporters in English, Malay, Mandarin and Teochew, asking voters of Punggol East to "work together to make a better Punggol East."
RP's Jeyaretnam said he was determined to bring "a real choice" and urged voters to be heard and represented in Parliament, while SDA's Desmond Lim said he knows the "heart and soul" of residents in Punggol East after having campaigned in the area since 2001.
Jeyaretnam revealed after his nomination that he would move to Punggol when elected to stay closer to his residents.
"We will be putting up a five-year plan to address the concerns of the residents. We can't promise millions of dollars unlike other parties," Jeyaretnam said.
"Support us, I will work for you on the ground and in the Government. I will give you a better deal," Jeyaretnam added.
Jeyaretnam will be revealing details of the five-year plan for Punggol East next week.
The loudest cheers from a boisterous army of WP supporters were reserved for Lee, who promised residents to serve them whole-heartedly and continue standing up for their rights.
"Vote for WP come 26 Jan and send me into parliament," she concluded.
Over the next nine days before Polling Day, all four qualified candidates are expected to go door-to-door in the single-member constituency to canvas for support and win the hearts and minds of over 31,000 voters in the constituency.
DPM Teo Chee Hean and MP in neighbouring Pasir Ris-Punggol GRC expects a "close fight" and hopes residents "will choose who can best represent them and their interests."
On paper, it looks like a straight contest between PAP candidate, surgeon Koh Poh Koon -- a self-described heartlander and former Punggol resident -- and WP's sales trainer Lee Li Lian, who last contested in Punggol in 2011, getting 41 per cent of votes.
But opposition SDA's Desmond Lim, who also contested Punggol in 2011 and received 4.5 percent of votes, could play the role of spoiler and dilute the share of opposition votes.
So too with Kenneth Jeyaretnam of the Reform Party, a former private hedge fund manager who contested the West Coast GRC in 2011, where he led his party to 33 per cent of votes against a PAP team.
When asked about the strategy and issues SDA will tackle, Lim said he will champion making amenities like hawker centres and child cares more available, easing traffic congestion and to voice out discontent of housing schemes for low income.
Lim says that he essentially wants the residents to have a choice.
“If they don’t like my product, then they don’t buy my product. However the company will still continue.”
Referring to his 50 strong-contingent of young supporters who carried SDA flags and waited calmly at the side throughout, he said he was not worried his supporters present seemed too young to vote.
"These are the supporters are the future of Singapore,” he said.
