Perikatan Demokratik Singapura
Registered: 3 July 2001
Symbol: Star & four rings
This political umbrella was conceptualized and centred around its chairman Chiam See Tong, whose SPP was its chief party. Originally, it aimed to unite all opposition parties under a single banner but the larger opposition parties turned down its offer. The alliance then kickstarted with four parties, SPP, NSP, PKMS and JPS. In 2007, NSP pulled out to redevelop its own brand name. In 2010, Chiam invited RP to join but other alliance leaders disagreed with his unilateral move to accept to RP's conditions, sparking internal strife. Closer to the 2011 General Election, SPP exited the group it once headed, leaving it as an insignificant player.
