In his first public function since being sworn in as Singapore's third prime minister, Lee said his predecessor Goh Chok Tong would help him get the new team off to a good start, Channel NewsAsia reported.
He said Goh would continue to develop Singapore's links abroad, using an extensive international network built up over the years, and would also help him "sell policies" at home.
He said his father, Minister Mentor Lee Kuan Yew, would no longer be involved in day-to-day running of the government, or even in setting directions for Singapore, but would remain in the Cabinet to keep current with younger ministers' thinking and with developments at home and abroad.
Deputy Prime Minister Tony Tan's main task would be to implement the national anti-terrorism strategy outlined last month.
Deputy Prime Minister S. Jayakumar, who is also minister for law, would chair a Cabinet committee on foreign policy matters that cut across different ministries and remain in charge of foreign policy issues involving legal negotiations or international adjudication.
