The core team of Singapore’s new generation of leaders will become evident next Sunday at the ruling People’s Action Party’s (PAP) internal elections, with the identity of the country’s fourth prime minister emerging soon after, South China Morning Post reports.  So far, three frontrunners have emerged for the top post:  Minister for Trade and Industry Chan Chun Sing, Minister of Finance Heng Swee Keat and Minister of Education Ong Ye Kung. The current prime minister, Lee Hsien Loong, the son of former prime minister Lee Kwan Yew, was elevated to deputy prime minister 14 years before becoming the country’s third premier. Lee junior, 65 and in power since 2004, has for some years voiced his wish to stand down before he turns 70. He has set 2022 as the year he will retire.
