By Amy Sawitta Lefevre BANGKOK (Reuters) - Thailand's anti-corruption agency may decide on Thursday whether to pursue charges against ousted Prime Minister Yingluck Shinawatra that could see her banned from politics, ending any hopes she may have of staging an electoral comeback. Yingluck was thrown out of office on Wednesday by the Constitutional Court for abuse of power, the latest twist in a nearly decade-long struggle for power between Thailand's royalist establishment and Yingluck's brother, former Prime Minister Thaksin Shinawatra. The National Anti-Corruption Commission (NACC) was meeting on Thursday to consider a separate case of negligence against Yingluck over a rice subsidy scheme that incurred billions of dollars in losses. \"Today, the NACC will decide whether former premier Yingluck is guilty or not in the rice case and how to proceed with the case,\" said an official at the NACC, who declined to be identified as she was not authorized to speak to the media.
