BANGKOK (AP) — A member of the elected Thai government ousted by last month’s coup formed an opposition group in exile Tuesday, invoking historical symbols of resistance and revolution while rejecting as illegitimate the new military regime.

There was no immediate sign the group established by former Interior Minister Charupong Reuangsuwan would attract much public support in Thailand, where the junta maintains a massive security presence and has detained people even for silent, brief acts of dissent.
