PM to decide whether to cancel Thaksin's passports : Tej

"It is a national issue, so the Foreign Ministry needs an instruction from the prime minister," Tej told reporters.

It is not unprecendented for a Thai PM to revoke diplomatic passport of former premier, he said.

Thaksin are now holding diplomatic and ordinary passports.

Tej made the statements protesters led by People's Alliance for Democracy rallied in front of the ministry, demanding the ministry to cancel all passports held by Thaksin and his wife; Pojaman. They said the couple were now criminal fugitives and were seeking asylum in England.
