It is genuinely unfortunate that Ong Kian Ming has left DAP. Over 14 years with the party, he served with distinction as MP for Serdang and later Bangi, as deputy international trade and industry minister, as an appointed member of the party's Central Executive Committee, and as an elected member of the Selangor DAP state committee. He was one of DAP's more policy-focused voices, a figure who brought academic rigour to political discourse.

His departure was not abrupt. He wrote a public resignation letter addressed to DAP secretary-general Anthony Loke, thanking the party for the opportunities it had given him. He thanked Tony Pua for inviting him to join DAP in 2012. He thanked Lim Guan Eng for nominating him as a candidate and appointing him deputy minister. He thanked the members and leaders of Serdang and Bangi. He wished everyone a "Happy Merdeka Day."

All of that was gracious. But the same letter contained a commitment that has drawn attention.

The Promise That Changed Everything

"I remain committed to fulfilling the promise I made on 10 January 2026, to help Khairy Jamaluddin campaign in GE16, if he is given a seat to run in," Ong wrote.

In January, Ong had gone further — he said he was prepared to take leave from work to campaign publicly for Khairy regardless of which party the former health minister represented.

A farewell that thanks DAP for 14 years of support, followed immediately by a pledge to campaign for a former Umno leader who may well contest against DAP itself.

He did not say "if Khairy joins DAP." He did not say "if Khairy shares our values." He said he would help Khairy regardless of which party he represented.

Ong is not the first politician to leave a party. He will not be the last. People leave for various reasons — ideological differences, internal politics, personal conviction. There is nothing inherently wrong with leaving.

The Debt That Was Owed

DAP gave Ong Kian Ming a platform when he was still an academic. Volunteers campaigned for him. Party workers gave their time. Voters trusted him — enough to send him to Parliament twice. The party made him a deputy minister.

He acknowledged all of this in his farewell letter. He expressed gratitude. He thanked the people who made his political career possible.

Gratitude, however, does not preclude leaving. Nor does it obligate anyone to stay forever. Political convictions evolve. Parties change. People change.

What is worth noting is that Ong's commitment to help Khairy came before his resignation. He had already made that promise in January. He had already decided that his personal commitment to a friend outweighed his party affiliation.

Whether that is principled or problematic depends on one's perspective. But it is a decision that invites scrutiny.

The Khairy Question

Khairy Jamaluddin is not a neutral figure. He is a former Umno Youth chief, a former health minister, and a politician who has spent most of his career on the opposite side of the political divide from DAP. Whatever his current ambitions, he remains a figure who represents a tradition of politics that DAP has spent decades opposing.

If Khairy contests against Pakatan Harapan — and it is entirely possible he will — Ong has already said he will campaign for him. That means campaigning against the very coalition that DAP is part of. That would mean campaigning against the party that gave him his political career.

Where is the principle in that?

Ong has said he is not joining another party and will not contest GE16. He says he will continue serving the nation through his podcast, advisory roles, and working with like-minded people.

That is his choice. But it does raise a question: when you thank a party for everything it gave you, and then immediately pledge to work against its interests, what exactly did that gratitude mean?

A Slight Disappointment

This is not about demanding loyalty to DAP forever. It is about consistency. It is about recognising that the people who helped you, the voters who trusted you, the party that invested in you — they might reasonably expect that your public commitments reflect some consideration of their interests.

Ong's resignation is a loss for DAP. He was a capable MP and a knowledgeable voice on policy. His departure reduces the party's bench of talent.

But the way he chose to leave — the public gratitude followed by the public commitment to campaign against the party's interests — is a decision that will be analysed and debated.

He is not the first politician to leave a party in this manner. He will not be the last. But the contrast between the farewell and the pledge is worth noting.

His political career is not over. He has said he will continue working in other capacities. What form that takes remains to be seen.
