Dr Mahathir on the attack

Smoking volcano: Dr Mahathir (right) stunned people inside and outside Umno when he announced he was withdrawing support for Najib.

Umno leaders are wondering whether it is just straightforward criticism or if there is a  bigger agenda to Tun Dr Mahathir Mohamad’s open attack on the policies of Datuk Seri Najib Tun Razak.

THOSE who move in the Tun Dr Mahathir Mohamad circle said the former premier had been critical of various government policies for some time now.
