We regularly do this during Cabinet shuffles, and the intent is to expose the office-holders to different portfolios to gain both breadth and depth to understand the intricacies of the issues, and to see things from different perspectives.

On 8 April 2021, Heng Swee Keat had announced that he was stepping aside as the 4G Leader citing "age" and "health" concerns.

As such, a Cabinet reshuffle occurred on 23 April 2021 where Lawrence Wong was announced to take over Heng Swee Keat as Finance Minister.

Lawrence also assumed responsibility of the Strategy Group in the PMO from Heng Swee Keat.

Thus, Chee Hong Tat was promoted to Minister of Transport and Grace Fu assumed responsibility as Minister-in-charge of Trade Relations on 18 January 2024 from S. Iswaran .
