Malaysias veteran former prime minister Mahathir Mohamad, who has been picked to lead an opposition bid for election victory, has been admitted to hospital with a chest infection, authorities said Saturday.
The 92-year-old, who has joined forces with his former protege-turned-nemesis Anwar Ibrahim in an attempt to topple scandal-tainted Prime Minister Najib Razak, "is being treated in the general ward for chest infection following a bout of cough," the National Heart Institute said in a statement.
