s Prime Minister Abhisit Vejjajiva said he would step down if he believed he was an obstacle to his country's stability. In a BBC interview released on Tuesday, he said the country's problems were not purely political and involved security and what he called terrorist problems, saying Thailand needs more than a short-term solution. He also said there were no plans to impose martial law to clamp down on weeks of protests to campaign for immediate elections. His comments came as Thailand's anti-government Red Shirts continued protests in a bid to thwart a feared military crackdown as the government talked tough against the protesters.
