City Harvest Church (CHC) founder Kong Hee, 49, and five others are on trial for allegedly misusing more than $50 million of church funds through sham bonds.

This includes $24 million to fund Kong's pop singer-wife Sun Ho's music career, and another $26.6 million to cover up the first amount

They are said to have done this through two companies run by long-time supporters of the megachurch - music production firm Xtron and glass manufacturer Firna.

Kong, former board member John Lam, 46, finance manager Sharon Tan, 38, former investment manager Chew Eng Han, 54, deputy senior pastor Tan Ye Peng, 41, and former finance manager Serina Wee, 37, face varying charges of criminal breach of trust (CBT) and/or falsifying accounts.

The defence started its case on Monday, with Lam the first to take the stand.

Prosecutors had sought to show how Xtron and Firna directors had simply done the bidding of the accused and rubber-stamped deals.

Meanwhile, the defence has argued that the transactions were legitimate, with the six accused acting "in good faith" on the advice of lawyers and auditors.
