The prosecution on Friday pushed for a jail term of five months for former civil defence force chief Peter Lim Sin Pang, saying that he had abused his position and damaged the reputation of the Singapore Civil Defence Force.

It also agreed to take into consideration seven of the remaining nine corruption charges Lim faces, after his lawyers made an offer. The other two charges will be withdrawn after he is sentenced.

Lim, 52, was convicted of one charge of corruption last week, for obtaining oral sex from Ms Angie Pang Chor Mui, 49 in exchange for furthering the business interests of her employer Nimrod Engineering.

But he faced nine other corruption charges involving two other women in their 40s - senior executive Esther Goh of information technology firm NCS, and Ms Lee Wei Hoon, who was a senior executive of technology company Singapore Radiation Centre. Both women had dealings with the SCDF at the time when Lim was commissioner.

The nine charges had been stood down earlier and was to be dealt with separately after the 52-year-old claimed trial to all of them earlier this year.

Lim will find out his fate on June 13 when the court delivers his sentence.

He faces a jail term of up to five years or a fine of up to $100,000, or both, for each charge.
