Here is the link to the petition. https://www.change.org/p/in-support-of-an-open-singapore-presidential-election-2017
Lim Tean, Secretary General of NSP, Tan Kin Lian, Goh Meng Seng and Syafarin Sarif have started this petition to the Govt stating that the next EP election should be in 2023 and not in 2017. The issue is how the 5 terms were counted, the govt starts counting from Wee Kim Wee but the petition and Tan Cheng Bock’s constitutional challenge disagrees with this, that it should start counting from Ong Teng Cheong as the first Elected President.
500 people have signed the petition and still counting meaning they don’t agree with the govt’s methodology or tracing it further back, they don’t agree with the AG office’s recommendation.
