Newly-elected Port Dickson MP Datuk Seri Anwar Ibrahim, 71, was sworn in as a lawmaker in the Dewan Rakyat on Monday morning. The PKR president-elect won the PD by-election engineered for his return to parliament by an overwhelming majority on Saturday, bringing him closer to the premiership promised to him by former foe, Prime Minister Tun Dr Mahathir Mohamad.
