PAP candidate Koh Poh Koon will wait for the Prime Minister to decide how he should contribute in the days ahead, but branch activists at Punggol East will continue to serve residents in the ward.
Asked about his plans after his by-election loss, Dr Koh told reporters Sunday morning: "Obviously, after this, we need to sit down and look at the results and think deeper.
"So I will await what the PM has decided before seeing where else I can contribute."
The colorectal surgeon said his team was proud that they had done their best, and that he had a strong local team.
As for the lesson he learnt, he said: "The important thing is to have a good, strong team and to continue to be sincere with residents.
"I think we have garnered 43 per cent of the votes having been on the ground for two weeks, I think that wasn't too bad."
Dr Koh spent the morning touring the estate on a bus, waving to supporters. He plans to spend time with family today, and return for reservist training on Monday where he is a commanding officer.
