Outspoken opposition activist and lawmaker candidate Suong Sophorn yesterday filed a lawsuit against Prime Minister Hun Sen, accusing him of faking identity documents and masterminding a plan to allow a large number of “illegal” immigrants from Vietnam to live in Cambodia.

Speaking outside Phnom Penh Municipal Court, the 26-year-old, who is president of the Cambodia National Rescue Party’s youth movement and a candidate in the upcoming National Election on July 28, claimed Hun Sen had arranged for Ministry of Interior officials to make an unspecified number of fake identity cards.

“I have enough evidence to claim [Hun Sen] . . . arranged fake identity cards for Yuon,” he said, referring to Vietnamese.

“Conversely, [some] Khmer children born in Cambodia do not have identity cards to use,” he added.

Ministry of Interior spokesman Khieu Sopheak denied the allegation and said Sophorn was simply provoking the CPP before the election.

“If the court finds out Samdech Prime Minister [Hun Sen] ordered cards be issued to Yuon or other foreigners, I will cut my neck,” he said, adding that Sophorn should be wary of defaming others lest he be counter-sued.
