Ong, known for his pivotal role in bringing the Formula 1 Grand Prix to Singapore, admitted on Monday to facilitating the obstruction of justice by helping former transport minister Subramaniam Iswaran settle a business class flight from Doha to Singapore. The renowned tycoon is reportedly implicated in offering lavish gifts to Iswaran, which included luxurious tickets to the F1 Grand Prix along with an extravagant trip valued at around S$20,850 ($16,188; £12,194).

Singapore’s strict regulations dictate that ministers cannot retain gifts unless they reimburse their market worth to the government, and they are mandated to disclose any gifts received from parties with whom they conduct business. Arrested alongside Iswaran in July 2023, Ong's charge sheets reveal that Iswaran received gifts totaling over S$403,000 ($311,882; £234,586), encompassing flights, accommodations, and event tickets, while he served on the F1 steering committee and acted as the principal negotiator for F1-related agreements.

Ong, who faces significant jail time – up to two years for assisting a public servant in receiving gifts and a potential seven years for obstruction of justice – is a notable figure in the hotel and property sector, having founded Hotel Properties Limited in the 1980s. The 77-year-old businessman, diagnosed with rare bone marrow cancer, has previously been allowed to begin traveling again for both health and professional reasons. As of April, Ong announced his decision to step down as managing director of HPL to better manage his health concerns, emphasizing the personal toll this scandal has taken on his life.
