According to The Star newspaper, a Kuala Lumpur court accused Mansor, 68, of receiving a bribe of MIR5 million (US$1.22 million) from Jepak Holdings at her home on December 20, 2016.
The money was an inducement for helping Jepak Holdings to obtain a project to install a solar power system in 369 rural schools in Sarawak. The project was worth MYR1.25 billion (US$305 million) invested in by the education ministry.
Under Malaysian law, if found guilty, Mansor will face a sentence of 20 years in prison or a fine equivalent to five times the bribe amount. She pleaded not guilty.
The court will resume on May 10.
