Thaksin's revoked passport is his last Thai traveling document after his diplomatic passport was terminated in the middle of December when the government under Prime Minister Abhisit Vejjajiva took office.
His ordinary passport was revoked April 12 after he used video link a abroad to provoke a group of red shirted protesters to disrupt the Asean summit last Saturday.
The foreign ministry has authority to recall any passports which the traveling holders could exploit it to facilitate their movement to hurt the country, Tharit said.
However, the termination of his passport did not affect Thaksin's Thai citizenship, he added.
Thaksin could no longer travel with Thai passport but he can ask for temporary traveling document from any Thai embassy or consult office in abroad if he wanted to return to Thailand, Tharit said.
