On 22 July 2007, thousands of protesters, mostly Thaksin supporters, demonstrated in front of Prem's house, calling for him to resign. When the demonstration exploded into violence, police cracked down and arrested several protest leaders, including an interim National Human Rights Commissioner and a former judge, both being former members of deposed prime minister Thaksin's political party. Afterwards, junta chief Sonthi Boonyaratklin visited Prem to apologize for the protests on behalf of the government. A day later, Prime Minister Surayud Chulanont, along with 34 members of his Cabinet, went to Prem's house to apologize to Prem for failing to ensure peace. Surayud accused the protestors of trying to bring down the highest institution of the country. Government spokesman Yongyuth Mayalap said Prem categorically denied the protestors' allegations that he was behind the military coup. According to Yongyuth, Prem said that the charges were repetitive, baseless and provocative.
