RM38 million defamation suit! That's what DAP MP Teresa Kok will face should she fail to apologise for her allegations of impropriety involving a politically-connected cargo company.

Malaysia Airlines (MAS) Dhaka-based general sales agent - Silkways Cargo Services Ltd - has served a legal letter to the feisty opposition politician demanding she immediately cease making allegations of weight cheating involving the cargo company.

In the four-page letter dated May 29, Silkways through its Bangladeshi legal firm Sobhan & Sobhan, called the MP to "retract and apologise" over her public statements made against Silkways in seven days.
