The woman at the centre of the corruption trial involving former Singapore Civil Defence chief Peter Lim Sin Pang arrived in court Monday morning.

The 52-year-old Lim is charged with corruptly obtaining oral sex from former Nimrod Engineering general manager Pang Chor Mui, in exchange for furthering the business interests of the technology company.

Ms Pang, who is in her 40s and a mother-of-one, is set to take the stand as a prosecution witness on Monday.
