In March 2004, Ranariddh privately proposed to Hun Sen that FUNCINPEC should join CPP in the new government as a junior coalition partner. Discussions between CPP and FUNCINPEC began on the composition of the coalition government and legislative procedures. An agreement was reached in June 2004, when Ranariddh walked out of his alliance with Rainsy, dropped his demands to reform the NEC and once again pledged to support Hun Sen as Prime Minister. Hun Sen also pressured Ranariddh into supporting a constitutional amendment known as a "package vote", which required MPs to support legislation and ministerial appointments by an open show of hands. While Ranariddh acquiesced to Hun Sen's demand, the "package vote" amendment was opposed by Sihanouk, Chea Sim, the SRP as well as several senior leaders within FUNCINPEC. After the "package vote" amendment was passed in July 2004, several FUNCINPEC leaders resigned in protest. Ranariddh, who remained as President of the National Assembly as part of the agreement, attempted to lure SRP leaders into defecting to FUNCINPEC with the promise of jobs within the government. At least one senior SRP leader, Ou Bun Long, caved into Ranariddh's enticements.
