Malaysia’s opposition leader Mahathir  Mohamed, a 92-year-old previous authoritarian ruler of the country, has defeated Prime Minister Najib Razak in a shock upset, winning 112 seats in Malaysia’s Parliament, the amount required for a majority.

Mahathir  Mohamed will become the oldest elected leader in the world, and ends a 60-year rule of Mr Razak’s National Front, which won 76 seats according to the Election Commission.

Mr Mohamed joined the opposition after being angered by a corruption scandal involving Mr Razak, but during his 20-year rule which ended in 2003 he was known for imprisoning opponents and subjugating the courts.
