Opposition MP Chiam See Tong has called on all opposition parties to contest as many GRCs and single member constituencies as possible in the next General Election. Political observers say that Toa Payoh-Bishan GRC may be up for contest due to its proximity to Potong Pasir while [SMU Assistant Professor of Law] Eugene Tan adds that residents in Toa Payoh-Bishan can see for themselves how Mr Chiam has been managing his constituency.
