Lawmakers Rafizi Ramli and Tony Pua - two of 1MDB's harshest critics - have been barred from leaving the country.

Pua, the Petaling Jaya Utara MP and a Public Accounts Committee (PAC) member, was stopped by immigration authorities at the KLIA2 today.

Speaking to Malaysiakini , Pua said he was supposed to board a flight to Jogjakarta, Indonesia.

Asked what reasons were given for barring him, he replied: "The immigration officer told me it was 'instructions from above'."

A check by Malaysiakini on the Immigration Department website showed that Pua's travel status was described as: " Sila rujuk kepada pejabat imigresen terdekat (Please refer to the nearest immigration office)."

Meanwhile, Rafizi, upon learning of Pua's predicament, ran his own checks on the same website and received the the same response.

"Therefore, I suspect that I too have been blacklisted and not allowed to leave Malaysia," he said in a statement today.

Rafizi and Pua are among the opposition figures accused of fabricating documents related to 1MDB for a smear campaign against Prime Minister Najib Abdul Razak.

They were implicated in a video confession by former Sarawak Tribune journalist Lester Melanyi, who claimed the opposition fabricated 90 percent of the documents in collaboration with whistleblower website Sarawak Report .

Rafizi and Pua have denied the allegation.
