BANGKOK - THAI Prime Minister Somchai Wongsawat must step down before anti-government demonstrators agree to talks on ending their occupation of Bangkok's main airport, protest leaders said on Wednesday.

'The condition is that the prime minister must resign first and then we are ready to hold talks,' Pibhop Dhongchai, a core leader of the People's Alliance for Democracy protest movement, told AFP.

'He must actually quit and it will depend on the outcome of negotiations before we decide to vacate Suvarnabhumi Airport,' he said, a day after protesters stormed the terminal building. -- AFP
