Set up by a WP splinter led by Seow Khee Leng, UF changed its name to SUF on 5 March 1982, at its 9th anniversary, to avoid confusion with UPF. In 1988, most of its members including Seow rejoined WP to combine forces and take on GRCs. Widely thought to have been dissolved, it was actually kept in the backburner. In 1990, Seow and others who concealed their dual membership left WP again to revive SUF, quietly renaming it DPP to promote it as a new party. A father-and-son pair defied party decision to stay away from the 1997 and 2001 General Elections and were expelled in 2002. In 2013, dissident SPP leaders led by Benjamin Pwee revived the party, although they temporarily returned to SPP in the 2015 GE. Pwee and several members crossed over to SDP in 2019, rendering DPP inactive again.
