Do you know that Mr Ong Eng Guan, one of the pioneer members of the People's Action Party received a $7,000 monthly salary for his position as Mayor of the Singapore City Council from 1957- 1958? This salary made him the highest paid mayor in the world! After factoring the total annual inflation, $7,000 in 1958 is a whopping $56,591 in present terms. This amounts to an annual salary of $680,000! However, this still dwarfs in comparison to PM Lee Hsien Loong's current $2.2 million salary!
