Thailand’s prime minister says he will submit an application Friday to dissolve the lower house of parliament, setting the stage for early elections.

Prime Minister Abhisit Vejjajiva says he will submit the dissolution decree to King Bhumibol Adulyadej for royal approval before going to Indonesia later Friday to attend a summit of the Association of Southeast Asian Nations.

Mr. Abhisit said he will give a news conference Monday after he returns, where he is expected to announce the actual dissolution. Elections must then be held within 45-60 days.

Thailand has been gripped by political turmoil since 2006, when the military staged a coup. The country has been politically unstable since, with sometimes violent street protests launched after past votes.
