BANGKOK: As Thailand grapples with the unexpectedly difficult task of naming a new prime minister, the most controversial former holder of the job, billionaire populist Thaksin Shinawatra, plans to return home next month from years of self-imposed exile, his daughter announced on Wednesday.

Thaksin's planned August 10 return, confirmed in a Facebook posting by his daughter Paetongtarn on the occasion of his 74th birthday, comes at a politically sensitive time, as the Pheu Thai party, regarded as the main vehicle for his political interests, is seeking to win enough support in parliament to have one of its leaders become Thailand's 30th premier.
