Thaksin Shinawatra, a divisive and compelling figure even in his years of exile, was once hailed as a champion of the common people. His recent moves have disillusioned followers.
The country went months without naming a new prime minister, only for Parliament to elect Srettha Thavisin, a candidate that many frustrated voters say represents the establishment.
After failing to choose a prime minister, Parliament will vote again as protesters gather outside. The process is a test for democracy in a nation with a history of coups.
