Blogger and social worker Ravi Philemon, 47, will be the Singapore People's Party (SPP) candidate for the Hong Kah North Single-Member Constituency (SMC), where he will square off against Senior Minister of State Amy Khor from the ruling People's Action Party.
Mr Philemon was unveiled on Saturday by the SPP chairman Lina Chiam at a walkabout in Bukit Batok where the party chief, opposition veteran Chiam See Tong, also made a rare appearance.
"SPP promised to put up a credible candidate for Hong Kah North SMC, which was a constituency traditionally contested by SPP," said Mrs Chiam.
"By fielding Ravi Philemon, we believe the party has fielded a very strong candidate to contest Hong Kah North against the PAP."
Mr Philemon said he was running because he believed he had a debt to Singapore. "I come from a disadvantaged family. Today, I have been able to climb up the social mobility ladder and be where I am thanks to opportunities available in Singapore," he said.
He added: "It is important to have checks and balances to make sure there is enough opportunities in the future."
The SPP is contesting three single-seat wards and is due to send a joint team to the Bishan-Toa Payoh GRC with the Democratic Progressive Party.
With his announcement, all candidates for SMCs that SPP intends to contest have been unveiled. Mrs Chiam will be contesting Potong Pasir and Mrs Jeannette Chong-Aruldoss is being fielded in Mountbatten.
But the Bishan-Toa Payoh team that will jointly consist members of the SPP and the Democratic People's Party remains up in the air.
Asked about this on Saturday, Mrs Chiam said: "The names of these candidates will be released in due course, and you will not be disappointed."
