Former premier Datuk Seri Najib Razak said it would be a wrong move to sell or shut down Malaysia Airlines Berhad (MAB), when met by reporters outside the Dewan Rakyat on Tuesday.

He added that the present administration should refer to the turnaround plan in place when he was heading Khazanah Nasional Berhad, the sole shareholder of the MAB.

Earlier, Prime Minister Tun Dr Mahathir Mohamad said the government was studying options for the national carrier, and a decision should be made "soon".
