BANGKOK, Thailand - Thailand's opposition Democrat Party says it has enough support to form a new government following a six-month political crisis that has paralyzed the country.

Party Secretary-General Suthep Thaugsuban announced today his party has the backing of more than half of the 400 lawmakers in the lower house, allowing it to form a government.

An activist group, the People's Alliance for Democracy, spearheaded mass demonstrations against prime minister Somchai Wongsawat's government which culminated in a weeklong siege of the capital's two airports that ended yesterday.

More than 300,000 travellers, including hundreds of Canadians, were stranded by the political showdown, which led to the resignation of the prime minister following a court ruling.

On Tuesday, the country's Constitutional Court found Somchai's People's Power Party, the Machima Thipatai party and the Chart Thai party guilty of committing fraud in the December 2007 elections that brought the coalition to power.
