| Officially JPS but submitted its name as SJP in some elections, it was set up by ex-UNF members dissatisfied with the leadership. Shortly after, it absorbed the bulk of UNF, which led to the revival of infighting and gradual weakening of the party. When erstwhile SDP MP Chiam See Tong became SPP's leader in 1997, several crossed over to SPP with the approval of those who remained behind. In 2001, it became an inaugural component of SDA along with SPP and others. However, after SPP pulled out of SDA in 2011, ex-JPS member Desmond Lim resigned from SPP and returned in order to stay within SDA. |
