Unlike his mentor, Najib made apologies for BN's past mistakes. Sorry seems to be the easiest word for him. But immediate responses from people suggest they do not believe in his sincerity because he had three years to make amends but did not. Even his Deputy was quick to play down his apology in the true arrogant spirit of Umno of not having to say sorry. Something to do with Ketuanan, I think.
I believe Najib is willing to do anything just to stay in power. So far, he had distributed public money to people to gain support. He does 'walkabouts' to show he is approachable. He has even apologized, but nothing of substance could be seen in terms of improving on transparency and accountability in mega projects, where public funds are being used to benefit party, leaders and cronies.
