Prime Minister Yingluck Shinawatra, Mr Thaksin’s younger sister, has submitted a letter to the Ombudsman asking for 30 more days to give the government’s clarification on the matter.
Raksagecha Chaechai, the Ombudsman's deputy secretary general, said the prime minister explained that the case was formerly under the supervision of Deputy Prime Minister Phongthep Thepkanjana who was in charge of the Foreign Ministry.
Mr Phongthep is no longer responsible for the Foreign Ministry and the authority has shifted to Deputy Prime Minister/Foreign Minister Surapong Tovichakchaikul, said Ms Yingluck in her letter to the Ombudsman.
He said the government was empowered to seek an extension of the deadline.
Mr Thaksin was sentenced in absentia to two years in jail for abusing his authority in the purchase of a plot of land on Ratchadapisek Road by his then wife, Khunying Pojaman Na Pombejra.
