Supreme Privy Council
In 2002, Chakrapong established a royalist party, the Khmer Soul Party. When the Khmer Soul Party failed to win a single parliamentary seat in the 2003 general elections, Charkapong rejoined Funcinpec and briefly served as Senator in 2005. In 2006, Chakrapong was expelled from Funcinpec and joined the Norodom Ranariddh Party. When the Cambodian government pursued legal investigations on the debts Chakrapong accumulated from his airlines, Chakrapong quit politics in 2007. Chakrapong, who was already a privy councillor to the Supreme Privy Council, then dedicated himself to humanitarian work and supporting royal activities. In 2013, Chakrapong was appointed member of the Constitutional Council of Cambodia by the King.
