PHNOM PENH — Preliminary results in Cambodia’s June 4 local, or commune, elections indicate a narrow win for Prime Minister Hun Sen’s Cambodian People’s Party. The CPP took 51% of the popular vote, giving it control of around 1,100 of the country’s 1,646 communes. But nearly half of all voters opted for the opposition Cambodian National Rescue Party, suggesting a close fight in next year’s parliamentary elections. The local elections were a dry run for the 2018 poll. Two days before the vote, Hun Sen led a huge CPP rally in Phnom Penh — a rare appearance from a leader previously so confident that he rarely campaigned. The CNRP emulated the CPP later the same day. Tens of thousands of both parties’ supporters rode around the capital in festive convoys of trucks and motorbikes around 5km long.
