Mr Wong is widely expected to be appointed as the PAP's first assistant secretary-general, taking over from Mr Heng, when the party announces its slate of CEC office-holders in the coming weeks. When Mr Heng assumed the role in 2018, it was seen as an indication that he was the frontrunner to be Singapore's next Prime Minister. Assoc Prof Tan said the PAP is likely to continue having a second assistant secretary-general, and that Mr Chan could be reappointed to the role.
