Malaysia's Mahathir becomes world's oldest leader aged 92
Malaysia's Mahathir Mohamad on Thursday became the world's oldest PM at the age of 92. Mahathir, who earlier led the country from 1981-2003, defeated scandal-hit Najib Razak in the general election, ending six decades of rule by a coalition he once led. The veteran led the opposition coalition, Pakatan Harapan, to its first election victory since Malaysian independence in 1957.
