According to the NEC, 99.7% of the eligible voters voted in the election.

Four political parties took part – the CPP, the Funcinpec Party of Prince Norodom Ranariddh, the Cambodian Youth Party, and the Khmer National United Party. Founded in 1999, the Senate has 62 seats, but voting was held for 58 seats only, as two senators had been appointed by King Norodom Sihamoni and two others will be appointed by the National Assembly (the lower house).

The official results will be announced on Saturday if there is no complaint from any political party.
