SINGAPORE - People's Action Party (PAP) MP Tin Pei Ling said she hopes "to have the opportunity" to continue to serve MacPherson, which has been carved out as a Single-Member Constituency (SMC) under new electoral boundaries unveiled on Friday.

Ms Tin is the incumbent MP for MacPherson.

MacPherson was part of the Marine Parade GRC helmed by Emeritus Senior Minister Goh Chok Tong in the last election in 2011. It will become an SMC in the next election.

Political pundits are watching with interest whether Ms Tin, a first-term MP who came under criticism in the last election, will be fielded in MacPherson SMC.

"Over the past four plus years, my team and I have been serving whole-heartedly, and working hard to help solve residents' problems and make MacPherson a better home," Ms Tin wrote in a Facebook post.

"We will continue to do so, and certainly hope to have the opportunity to continue serving MacPherson moving forward."

Ms Tin said it will be "business as usual" even though she is expecting a child soon.

"I may be physically absent for a short while because of the confinement period, but I have a team in place and communication channels set up, so it will be 'business as usual'," she wrote. "I have also made arrangements for my MP colleagues to cover me during this brief period."

She added: " I hope that MacPherson residents will continue to give me your strong support."

Many opposition parties would be keen in MacPherson if PAP decides to field Ms Tin, said law don and former Nominated MP Eugene Tan.

He added: " If being a first-time mum, she goes on the campaign trail shortly after delivery, that may go down well with some voters."
