The awkward 11-party alliance emerged after both camps saw their interests align in the wake of a May election that produced a stunning win for Move Forward, a party that advocated changes to a law forbidding criticism of King Maha Vajiralongkorn and other top royals. The royalist parties wanted to keep Move Forward out of power, while Thaksin sought to strike a deal that would allow him to return to Thailand after 15 years of shuttling between Hong Kong, Singapore, Dubai, and London.

“Pheu Thai is the most powerful party to battle the emergence of Move Forward, after the electoral defeat of the conservative parties,” said Yuttaporn Issarachai, a political scientist at Sukhothai Thammathirat Open University. “As the saying goes, the enemy of my enemy is my friend.”

Thaksin’s return will mark a full-circle moment in Thailand’s political drama, which has seen a cycle of coups and deadly street protests erodes the nation’s competitiveness as a Southeast Asian manufacturing destination since the turn of the century. Foreign investors have dumped about $3.8 billion of Thai stocks this year, triggering an almost 9% slump in the main stock index to rank it among Asia’s worst performers.
