Samak's government actively sought to amend the 2007 Constitution, and as a result the PAD regrouped in May 2008 to stage further anti-government demonstrations. The PAD accused the government of trying to grant amnesty to Thaksin, who was facing corruption charges. It also raised issues with the government's support of Cambodia's submission of Preah Vihear Temple for World Heritage Site status. This led to an inflammation of the border dispute with Cambodia, which later resulted in multiple casualties. In August, the PAD escalated its protest and invaded and occupied the Government House, forcing government officials to relocate to temporary offices and returning the country to a state of political crisis. Meanwhile, the Constitutional Court found Samak guilty of conflict of interest due to his working for a cooking TV programme, terminating his premiership in September. Parliament then chose PPP deputy leader Somchai Wongsawat to be the new prime minister. Somchai is a brother-in-law of Thaksin's, and the PAD rejected his selection and continued its protests.
