The People's Action Party (PAP) candidate who twice lost in election bids in the Hougang single-member constituency appears unlikely to contest there for a third time.
Mr Desmond Choo, 36, was this week named as the second adviser to grassroots organisations in Tampines East, a ward in Tampines GRC.
Its MP is former national development minister Mah Bow Tan, 66, who stepped down from the Cabinet after the 2011 General Election.
The announcement of Mr Choo's move came in a People's Association (PA) statement yesterday on the appointment of grassroots leader Goh Chee Koh, 69, as adviser in Hougang, succeeding Mr Choo.
Mr Goh, who served as a grassroots volunteer in Punggol for 40 years, including as Punggol Central Citizens Consultative Committee chairman, took over in Hougang on Tuesday.
The statement also said that gynaecologist and grassroots leader Kee Wei Heong, 64, took over yesterday as grassroots adviser in Aljunied GRC's Kaki Bukit ward.
He succeeds Mr Ong Ye Kung, 44, who was part of the five-man PAP team that lost to the Workers' Party (WP) in Aljunied GRC in the 2011 polls.
Mr Ong, who served as adviser in Kaki Bukit for over three years, said in July that he had moved to Sembawang GRC.
He has no official position there, but it was previously reported that he would help at Marsiling ward, whose MP is Senior Parliamentary Secretary (Education and Manpower) Hawazi Daipi, 60.
Mr Ong and Mr Choo remain chairmen of the PAP Kaki Bukit and Hougang branches respectively.
