Singapore's former Transport Minister S. Iswaran has been charged in court for graft, the anti-corruption agency said on Thursday, in one of the most high-profile graft cases involving a minister in the Asian financial hub in decades. The Corrupt Practices Investigation Bureau (CPIB), in a statement, said Iswaran, who was arrested in July last year, is alleged to have obtained kickbacks valued at S$384,340.98 ($286,181) from property tycoon Ong Beng Seng, partly to advance Ong's business interests. Charge sheets show the favours include tickets to football matches, musicals, flights on Ong's private plane and tickets to the Singapore Formula 1 Grand Prix.
