Indian-origin Singapore-born economist Tharman Shanmugaratnam was on Thursday sworn in as the ninth president of the predominantly Chinese and economically prosperous city-state.
Indian-origin Chief Justice Sundaresh Menon administered the oath of office to President Tharman at a ceremony held at Istana, a 154-year-old palace in the heart of Singapore's Shopping and Hotel Belt of Orchard Road. The Istana is the official residence of the President of Singapore.
