Cambodia’s Senate elections officially kicked off on Sunday with candidates coming from the two major parties in the country: the ruling Cambodia People’s Party and the opposition Sam Rainsy Party. The country’s 61-member upper house of Parliament is chosen by local officials and members of the National Assembly, or lower house. Two seats are appointed by King Norodom Sihamoni and two by the National Assembly. Since early morning, 33 constituencies in 8 regions nationwide were open for voting under the observance of international and domestic reporters. Cambodian voters are confident that the Cambodian People’s Party will win the elections. The initial results will be announced at a press briefing later in the day.
