BANGKOK, Aug. 22 (Xinhua) -- Thailand's caretaker Prime Minister Thaksin Shinawatra said on Tuesday that he has not yet made a final decision on his political future.

    When presiding at a police ceremony here on Tuesday, the caretaker prime minister said that he had not yet made up his mind on his political career.

    "I still don't know whether I should retire from politics by the end of this year, or continue my political work in coming years," he said.

    "Whatever a final decision I'll make, I'll, however, never retire from being a police officer," said the police lieutenant colonel-turned-leading politician.

    Thaksin said that police officers as law enforcers -- and all other Thais -- should honestly observe their duties and be kind to one another, as advised by the King, for the sake of national peace and order.

    Responding to journalists at his Thai Rak Thai (TRT) Party headquarters after the Police Club's ceremony, the caretaker premier said briefly that he was too tired to give any interview.

    "Please don't ask me any question. I'm so tired at the moment," he told the reporters -- apparently avoiding revealing any more information.

    Security measures for the prime minister have been tightened following confrontations between the pro- and anti-Thaksin groups here over the past days in Bangkok, which caused two injuries.

    Confrontations were also reported when the caretaker premier visited the country's northeastern and northern regions earlier this month.

    However, Phimuk Simaroj, deputy Thai Rak Thai spokesman, told local media that Thaksin on Tuesday assured other party leaders that he would remain as party leader and contest the election as No. 1 candidate on the party list. Enditem
