On Sunday (Nov 19), the People's Action Party (PAP) will hold its biennial convention. Prime Minister Lee Hsien Loong will address thousands of party members at the end of what has been a relatively choppy year for the ruling party, which has governed Singapore since 1959. Mr Lee, who is the party's secretary-general, is expected to rally his troops to stride confidently into 2018, an important year for the party and for Singapore, as a major Cabinet reshuffle is likely to shed further light on the question that preoccupies the mind of every political observer: Who from the fourth generation of PAP leaders will emerge as the next prime minister?
