Bersatu information chief Wan Saiful Wan Jan has challenged Malacca BN chief Ab Rauf Yusoh to disavow BN adviser Najib Abdul Razak over the latter's alleged "greed".

"If Rauf keeps quiet, therefore it is assumed that he and BN support Najib's greed. What guarantees do we have that he will not emulate Najib?

"The people of Malacca can evaluate BN's behaviour. Some of them will never change. I'm confident that the people of Malacca will choose wisely this Saturday," Wan Saiful said in a post on his Facebook page last night.
