The four Malacca DAP lawmakers who quit the party last Sunday have turned down offers from BN to dish the dirt on their former party.

Kota Melaka MP Sim Tong Him said state Chief Minister Idris Haron had invited him and three assemblypersons who had quit, to speak at a BN forum.

"The chief minister (Idris) had openly invited us to speak ill about DAP, at a BN forum and we are saying 'no' to him.

"This is ridiculous. We have reiterated that we will never support BN, moreover Umno," he told Malaysiakini.
