Anucha Burapachaisri, the prime minister's deputy secretary-general and acting government spokesman, has resigned to fill a vacancy as a list MP of the United Thai Nation Party.
He tendered his resignation on Monday morning and met caretaker Prime Minister Prayut Chan-o-cha to say farewell.
Gen Prayut gave him his blessing and wished him well in performing his new duties to the best of his ability and for the good of the country and the people, Mr Anucha said.
Mr Anucha said he thanked the prime minister for entrusting him with the job of deputy secretary-general for political affairs and twice as government spokesman during the past three years. As a PM's deputy secretary-general, he was assigned to oversee foreign affairs, coordinate political work and supervise the Office of the Spokesman.
He said the prime minister had redistributed his responsibilities among the three remaining deputies.
Mr Anucha's promotion up the party list fills the vacancy for an MP caused by the resignation of party leader Pirapan Salirathavibhaga, who was top of the party list.
He said he expected to received a letter from the parliament certifying him as a new list MP of the United Thai Nation Party on Monday. He would report to the secretariat of the House of Representatives on Wednesday and jattend the parliamentary session in voting to select the new prime minister on Thursday.
