6. Chiam See Tong – Net Worth: S$48.7 million
It’s nice to see an opposition minister also on this list.
At 82 years of age, Chiam See Tong held the title as the longest serving opposition Member of Parliament of Potong Pasir SMC from 1984 to 2011.
He only recently ceded the title to Worker’s Party Low Thia Khiang, who has just passed the 27th year mark of service as an Opposition MP this year.
Chiam was the founding leader of the Singapore Democratic Party, as well as the Singapore People’s Party.
