Thailand's interim Prime Minister Surayud Chulanont has completed the list of his first cabinet and submitted it for royal endorsement, a spokesman said Sunday.

According to newspaper Bangkok Post, spokesman Yongyuth Maiyalarb said the prime minister and aides were waiting for the King to endorse the cabinet list.

Surayud, who was sworn in as Thailand's 24th prime minister on Oct. 1, was expected to announce the lineup immediately after receiving the king's approval, which "may be on today (Sunday) or tomorrow", Yongyuth was quoted as saying.

Surayud said last week he and the new ministers are to be sworn in on Tuesday after being granted an audience by the King Bhumibol Aduyaldej.

The new cabinet led by the designated premier will exist for about one year pending the completion of a new Constitution and a general election, which was expected to be held late next year, according to the schedule drafted by the Council for National Security which led the Sept. 19 coup ousting former PM Thaksin Shinawatra's government and annulled the 1997 Constitution.
