“In Russia, they have the oligarchs and China the Princelings. In Singapore, we have the Siblings.”

// UPDATE (4 Sept 2015):
Will update the bigger image later (Chew siblings; grandchildren of Tan Chin Tuan).

FIRST COLUMN
1. Alan Chan Heng Loon, Public Service Commission (PSC) Member and former principal private secretary to Lee Kuan Yew, has two “illustrious siblings“: Professor Chan Heng Chee and Chan Heng Wing.
According to Singapore’s Constitution and PSC’s 2012 Annual Report:
The Public Service Commission (PSC)’s constitutional role is to appoint, confirm, promote, transfer, dismiss and exercise disciplinary control over public officers in Singapore.
It considers the suitability of candidates for appointment as Chief Executive Officers of Statutory Boards; it is also responsible for the planning and administration of scholarships provided by the Government of Singapore.

2. Ho Ching, wife of PM Lee Hsien Loong, has two brothers and a sister. Her sister is Ho Peng and one of her brothers is Ho Sing.
3. Teo Chee Hean has three sisters by the names of Hee Lian, Chai Lian and Swee Lian.
There is a Teo Swee Lian (director) in Singtel who was formerly a Special Advisor in the Managing Director’s Office at the Monetary Authority of Singapore (MAS). There is a Teo Hee Lian who was formerly the Director of Institute of Public Administration and Management (IPAM). This Teo Hee Lian has had “extensive experience writing cabinet memoranda, parliamentary replies, reports, papers, minutes of meetings, and speeches.”
Will update this section if anyone can verify that these two ladies are Teo Chee Hean’s sisters. Images below from CSCollege and Singtel.
4. Richard Ong and Charles Ong are Chinese-Malaysian brothers. Charles Ong spent 10 years managing investment projects for Temasek Holdings, and was described as the “right-hand man” to Temasek chief Ho Ching.
The last two funds Richard led or co-led (in 2011) raised around $5 billion combined. At a 2 percent management fee — an industry standard — that’s $100 million in annual fees alone.
According to Wikipedia and China Economic Review:
. . .the true reason that the China Securities Regulatory Commission (CSRC) denied Goldman permission to name [Richard] Ong to his new position was due to his family ties to Singaporean sovereign wealth fund Temasek Holdings and his own role in the money-losing sale of former Thai prime minister Thaksin Shinawatra’s Shin Corporation to Temasek.
- NOTE: Ho Ching’s (CEO of Temasek Holdings since 2004; wife of PM Lee Hsien Loong; on the Forbes Power Woman list every year since 2004) mother, Chan Chiew Ping, was from Taiping, Malaysia.
SECOND COLUMN
1. Ng Chee Meng has two notable brothers: Ng Chee Khern and Ng Chee Peng (both were President’s Scholars). Ng Chee Khern was Chief of Air Force from 2006 – 2009. Ng Chee Peng was Chief of Navy from 2011 – 2014, and was appointed the CEO of CPF in Jan 2015. Former defence chief, Ng Chee Meng, has been touted as a potential office-bearer.

As Roy Ngerng wrote in a FB post:
“Ng Chee Meng is expected to run for the PAP and would be the highest-ranking military officer to run for election. He could even potentially become a prime minister. This means that he could head the government. If so, the Ng family would control the government, the military and our CPF.“
2. Dr. Yaacob Ibrahim has a sister, Zuraidah Ibrahim (political deputy editor at The Straits Times, married to Cherian George). Yaacob and Zuraidah have a brother, Ismail Ibrahim, who was the first Malay President’s Scholar in SIngapore. Thanks to The Unseen Singapore for making the original identification.
3. Kwa Soon Bee, former Permanent Secretary for Health and Director of Medical Services, is a brother of Kwa Geok Choo (Mrs. Lee Kuan Yew). Kwa Soon Chuan was the first local appointed to the Colonial Administration. He is a brother of Kwa Geok Choo.
4. Lee Su Shyan, Money Editor / Business Editor at The Straits Times, is said to be the sister of Lee Yi Shyan. Will update this section if anyone can provide more verification.
THIRD COLUMN
1. Raymond Lim Siang Keat is the brother of Benny Lim, former ISD director.
2. Thio Shen Yi, President of the Law Society (2015), is the brother of Thio Li-Ann.
Thio Li-Ann’s views have been described as “anti-gay.” She described homosexuality as a “gender identity disorder,” said anal sex was akin to “shoving a straw up your nose to drink,” and opposed the repeal of a law in the penal code — known as Section 377A — that criminalizes sex between men.

In June of 2017, Lee Hsien Yang and Lee Wei Ling (siblings of PM Lee Hsien Loong) made the following public statement:
“We have no confidence in PM Lee Hsien Loong and are worried about Singapore’s future.”
