People's Action Party (PAP) Bukit Batok MP David Ong, who resigned suddenly yesterday, is believed to have had an extramarital affair with a woman who is a grassroots leader in his ward.
From accounts of those who knew them, it seemed the reported affair started some time after the general election. The woman is understood to be Ms Wendy Lim, 41, who works in a logistics firm and has been active in the constituency for some time.
A source said Mr Ong and Ms Lim, who are both married, were spotted together at last year's Formula One race.
Photographs on the Facebook page of Bukit Batok PAP Women's Wing showed that she had been participating in grassroots activities in Bukit Batok and supported the party during last September's general election campaign.
Ms Lim, who has children, had also posted photos of her and Mr Ong, taken at Keming Primary School during last year's general election, on her own Facebook page.
Sources told The Sunday Times that Ms Lim was active in constituency events.
Mr Ong's affair with her was also said to have gone on for several months, but came to light only recently.
After news broke yesterday of his resignation, Ms Lim made her Facebook page private, then later removed it completely.
A short profile of her on her company's website was later also removed. She holds a management position in her company and is in charge of sales.
A short curriculum vitae that was on the site before it was removed listed her as a former flight stewardess who graduated with a degree in management from the University of London in the United Kingdom.
When The Sunday Times visited Mr Ong's home in the east, a domestic helper said he was not in.
At Ms Lim's condominium in the west late last night, a young girl was at the door. When asked if a Ms Wendy Lim lived there, the girl closed the door immediately.
A few minutes later, a woman came by the flat and asked to be let in. Asked if Ms Lim lived there, she paused before saying no.
