=== 2004 presidential election ===
The PPP originally did not have a presidential candidate in mind for the [[2004 Indonesian presidential election|2004 presidential election]]. They had expected that Hamzah would be picked as Megawati's running mate and continue the Megawati/Hamzah President/Vice President partnership. Megawati however, chose NU Chairman [[Hasyim Muzadi]] as her running mate.

The PPP then continued to wait, still expecting that Hamzah Haz would be picked as a vice-presidential candidate. Finally, a day before the registration of presidential/vice-presidential candidates was closed, Hamzah moved forward and became the PPP's presidential candidate.<ref>{{cite web |title=Semangat Agum, Keraguan Hamzah (Agum's Enthusiasm, Hamzah's Doubts) |newspaper=Tempo |url=http://www.tempo.co.id/majalah/free/pilpres/hmz-1.html |archive-url=https://web.archive.org/web/20160305060939/http://tempo.co.id/majalah/free/pilpres/hmz-1.html |archive-date=5 March 2016 |language=id |url-status=dead }}</ref> His running mate was Agum Gumelar, who served as Minister of Transportation in Megawati's Cabinet. Hamzah's presidential run was unsuccessful as he received only 3.1% of the vote and came fifth.

In August 2004, the PPP announced that it was forming a national coalition with the PDI-P, Golkar, the [[Reform Star Party]] (PBR) and the [[Prosperous Peace Party]] to back Megawati to win the presidential run-off against Susilo Bambang Yudhoyono. Yudhoyono however would emerge victorious and the PPP would defect from the national coalition to Yudhoyono's camp. They were rewarded by being given cabinet places.
