In 2005, Viroj Nualkhair was dismissed from the KTB after incurring over 40 billion baht in problem loans. Sondhi then began criticizing Thaksin using the media under his control, including satellite broadcaster ASTV. He founded the People's Alliance for Democracy, aimed at overthrowing the Thaksin government. The PAD cancelled their activities after a military coup overthrew Thaksin. However, when Thaksin-affiliated parties won a post-coup election, and vowed to revise the new constitution, which they claimed was 'undemocratic', the PAD reformed and renewed its protests. In 2008, Sondhi and PAD demonstrators occupied Government House and barricaded themselves inside for months. They later seized Don Muang Airport and Suvarnabhumi Airport and closed them for several days, stranding thousands of travelers. At the height of the protests, the PAD declared the only person they would accept as Premier was Abhisit Vejjajiva, leader of the opposition Democrat Party. The protests ended when the Constitutional Court banned the People's Power Party for corruption. Army commander and co-leader of the 2006 coup, General Anupong Paochinda, pressured several PPP MPs to switch to the Democrat Party, allowing Abhisit to form a government and become Prime Minister. PAD leader Khamnoon Sitthisamarn called Abhisit's premiership a "genuine PAD victory" and a "Anupong-style coup."
