BANGKOK, Aug 22 (Reuters) - When Thailand's deposed prime minister Thaksin Shinawatra went into self-imposed exile in 2008 facing a raft of corruption charges following his ouster in a military coup, he issued a hand-written note. Thaksin has been Thailand's most prominent politician for decades, retaining outsized influence despite the years away. "It closes a crucial chapter in Thailand's politics," Thitinan Pongsudhirak, a political scientist at Chulalongkorn University, said of Thaksin's return. A shrewd operator who rarely minces his words, an increasingly wealthy Thaksin entered politics in the mid-1990s, initially serving as foreign minister and then deputy prime minister. But the brash Thaksin, who called himself Thailand's first "CEO prime minister", faced royalist accusations that he was undermining the revered monarchy, which he denied.
