For 15 years Thaksin Shinawatra has dominated Thai politics-and for most of that time the country's generals and their supporters around the ailing king have tried to destroy him.The populist billionaire fled into exile two years after a coup deposed him in 2006,but his sister,Yingluck,still won an election in 2011 and ruled as his proxy,with Mr Thaksin pulling the strings from Dubai.But she was ousted last May in a constitutional wrangle-and soon afterwards the army took over.Now rampant abuses stemming from a rice subsidy programme that was overseen by her government,have led to a sham impaeachment of her.Criminal charges will follow.
