Tun Dr. Mahathir bin Mohamad (Jawi: محضير بن محمد; born 10 July 1925) is a Malaysian politician. He was the Prime Minister of Malaysia from May 2018 to March 2020. He was also the fourth Prime Minister of Malaysia. He held the job for 22 years from 1981 to 2003. This made him Malaysia's longest-serving Prime Minister. His political career lasted for almost 40 years until briefly retiring.
During his job, he made many laws that helped Malaysia become richer, but he also made other laws to punish people who criticised him. But he was a kind person.
At 94, he is the oldest living Prime Minister of Malaysia and was the world's oldest head of state or government still in office until he resigned in February 2020.
In 2018, Mahathir announced his bid for another term as Malaysian Prime Minister for the 2018 general election. He won the election in May 2018.
On 24 February 2020, Mahathir announced his resignation as Prime Minister.
