Many believe that the US president is the highest income among the world's presidents and leaders by spending $ 400,000 a year, but Donald Trump earns only $ 1, after promising to donate his annual income and fulfilling the promise.

But which of the world's leaders is the highest?

Singapore's 67-year-old Prime Minister Lee Hsien Loong is still the world's biggest paycheck, with an annual income of $ 1,700,000, or 142,000 a month.

He is the world's highest-paid figure among the world's leaders. He was born on February 10, 1952 and is Singapore's third prime minister. He has served as secretary-general of the Singapore People's Party and has been prime minister since August 2004.

The son of Singapore's founder, Lee Hsien Loong, is expected to leave power after elections to be held by 2021.
