Albert Tei, the businessperson who has implicated several high-ranking Sabah politicians in a mining licence scandal, has reiterated his challenge for the leaders to prove his claims wrong. 

In particular, Tei singled out Parti Bersatu Sabah (PBS) acting president Dr Joachim Gunsalam and the party’s deputy president Jahid Jahim, inviting them to disprove his allegations through formal investigations.
