BANGKOK, Thailand — Thailand’s main opposition party said Saturday that it plans to form a government with the help of defectors from the ruling coalition, a move certain to appease an anti-government group that recently paralyzed the capital, shutting down its main international airport for a week.
The opposition Democrat Party announced it had mustered the backing of 260 lawmakers in the 400-seat lower house, allowing it to form a government with Oxford-educated party leader Abhisit Vejjajiva as prime minister.
But the party’s apparent triumph, managed during a still-chaotic situation the day after Bangkok’s Suvarnabhumi airport reopened, will not be sealed until Parliament meets within the next 30 days to endorse Abhisit and the five-party coalition behind him. The former ruling party said it would not give up the fight.
The Democrat Party is supported by the People’s Alliance for Democracy, an activist group that headed mass demonstrations against several recent governments led by exiled former Prime Minister Thaksin Shinawatra and his allies. The protests culminated in a week-long siege of the capital’s two airports.
The Democrats cobbled their coalition together against a somber backdrop: Thailand’s revered 81-year-old King Bhumibol Adulyadej, regarded as a cornerstone of stability, is ill. It was feared that if the ruling coalition had selected a new prime minister close to Thaksin, that could again ignite mass protests.
But for now it appears the opposition has the upper hand.
Democrat Party Secretary-General Suthep Thaugsuban said at a news conference that negotiations with other parties had been “the smoothest discussion” he has ever had because everyone realized the country’s stability was at stake.
The Democrats were expected to face problems if they form a new government amid Thailand’s polarized political arena.
Sombat Chanthonwong, a political science professor at Bangkok’s Thammasat University, said many would find it difficult to accept Abhisit as the new prime minister because he did not emerge from an electoral contest.
British-born Abhisit, 44, is an articulate, sophisticated politician, but critics say he is out of touch with ordinary people, particularly the rural majority, and lacks charisma. His party’s supporters include Bangkok’s middle class, influential military figures and foreign investors who see him as a stabilizing force.
