Sam Rainsy, the self-exiled leader of a banned Cambodian opposition party, was not allowed to board a flight on Wednesday to Jakarta, Indonesia, from Kuala Lumpur, but said he now plans to fly there on Thursday.

"I missed my flight from Kuala Lumpur this afternoon but will catch another flight tomorrow morning for Jakarta," Sam Rainsy posted on Twitter, hours after Malaysia Airlines said in a statement that it denied him boarding on instructions from Indonesian authorities.

The airline later confirmed that the co-founder and acting president of the Cambodia National Rescue Party is now allowed to leave for Jakarta on one of its flights.

Sam Fernando, spokesman of the Directorate General of Immigration at the Indonesian Ministry of Law and Human Rights, told reporters in Jakarta, "There was no order to bar him from entering Indonesia."

Wanted by Cambodian authorities for allegedly plotting a coup, Sam Rainsy, who is based in Paris, had been prevented from boarding a Thai Airways flight from the French capital to Bangkok last Thursday on the Thai prime minister's order and instead flew into Malaysia on Saturday.

He had wanted to head to Bangkok and from there cross overland into Cambodia where he hoped to lead a peaceful "popular uprising" against strongman Prime Minister Hun Sen's government.
