The Lawyers Council of Cambodia has turned down a request to replace the two Cambodian lawyers defending the seven Thais facing trial in Phnom Penh with Thai lawyers, Foreign Ministry spokesman Thani Thongphakdi said on Wednesday.
The request was made by legal advisers of the Thai Patriots Network.
Mr Thani said this means the seven Thais will continue to be defended in court by the two Cambodian lawyers hired by the Thai embassy.
He said the lawyers were discussing a possible appeal to the Supreme Court with Veera Somkwamkid, the only arrested Thai still in detention. He was denied bail by the Appeals Court.
The Thai embassy would do all it could to help Mr Veera, he said.
Mr Thani also said it was still not clear whether or when the Phnom Penh court would call the next hearing.
Mathurapojana Itharong, deputy director-general of the Consular Affairs Department, and a team of psychiatrists left for Phnom Penh on Wednesday morning to meet the six Thais who have been released on bail and examine their physical and mental health.
Karun Saingam, an adviser of the Thai Patriots Network, also left for the Cambodian capital to visit Mr Veera.
