PHNOM PENH (REUTERS) - The ruling Cambodian People's Party (CPP) said on Monday (July 30) it had won all 125 parliamentary seats up for grabs in a general election that critics have called a sham.

"The CPP won 77.5 per cent of the votes and won all the parliamentary seats," CPP spokesman Sok Eysan told Reuters by telephone.

On Sunday, the CPP said it had won "at least" 100 seats.

The White House said it would consider steps, including an expansion of visa curbs on some Cambodian government members, in response to "flawed elections" in which Prime Minister Hun Sen faced no significant challenger.

The opposition said in Jakarta on Monday the result of Cambodia's general election must be fully rejected by the international community.

"29 July 2018 marked the death of democracy in Cambodia, a dark new day in recent history," Ms Mu Sochua, vice-president of the Cambodia National Rescue Party (CNRP), told a news conference in Jakarta.

"The result announced by the CPP and the National Election Committee must be fully rejected by the international community," Ms Mu Sochua said.

The CNRP was dissolved by Cambodia's Supreme Court in November after it was found guilty of trying to overthrow the government, charges it denies.
