A former Singaporean cabinet minister pleaded guilty to charges of receiving illegal gifts Tuesday, in the Asian financial hub’s first ministerial criminal trial in nearly half a century.

Former Transport Minister S. Iswaran pleaded guilty to one count of obstructing justice and four of accepting gifts from people with whom he had official business. The court set Oct. 3 for sentencing, Channel News Asia reported.

Iswaran, 62, was initially charged with 35 counts but in a twist at the start of the trial, prosecutors said they would proceed with only five, while reducing two counts of corruption to receiving illegal gifts. Prosecutors said they will apply for the remaining 30 charges to be taken into consideration for sentencing. No reasons were given for the move.

Iswaran received gifts worth over 74,000 Singapore dollars ($57,000) from Ong Beng Seng, a Singapore-based Malaysian property tycoon, and businessperson Lum Kok Seng.  The gifts included tickets to Singapore’s Formula 1 race, wine and whisky and a luxury Brompton bike. Ong owns the right to the local F1 race, and Iswaran was chair of and later adviser to the Grand Prix’s steering committee.

The Attorney-General’s Chambers said it will decide whether to charge Ong and Lum after the case against Iswaran has been resolved.

In mitigation, defence counsel Davinder Singh asked the court to limit any jail term to no more than eight weeks, according to CNA. He said Iswaran had no motive in accepting the gifts other than personal friendship with the men, but he recognized it was wrong to do so and admitted guilt after the graft charges were dropped. There was no suggestion that the government’s impartiality and integrity had been undermined, Singh added.

But prosecutors called for a jail term of 6-7 months. Deputy Attorney General Tai Wei Shyong said in his submission that not punishing such acts would send a signal that such acts are tolerated. Singapore ‘s ministers are among the world’s best-paid. Although the amount involved in Iswaran’s case appeared to be relatively minor, his indictment is an embarrassment to the ruling People’s Action Party, which prides itself on a clean image.

The last Cabinet minister charged with graft was Wee Toon Boon, who was found guilty in 1975 and jailed for accepting gifts in exchange for helping a businessperson. Another Cabinet minister was investigated for graft in 1986, but died before charges were filed.

Iswaran had resigned just before he was charged. His trial comes just over four months after Singapore installed new Prime Minister Lawrence Wong after Lee Hsien Loong stepped down after 20 years.

Lee has said before he stepped down that Iswaran’s case was dealt with vigorously according to the law and vowed to uphold his government’s reputation for honesty and incorruptibility. The case could cast a shadow on the PAP ahead of general elections due by late 2025.
