His Majesty the King sprinkles holy water on a crowd at the Grand Palace on Monday night.

BANGKOK — The royal household announced a number of reassignments Monday in a reshuffling of the ranks.

Six palace aides working under His Majesty the King were stripped of their rank, some due to alleged misconduct, while five officials were promoted by the monarch for their service. Nineteen civil servants also left the royal household, four of them senior officials known as grand chamberlains.

Among the six military officers who lost their status were two officials, Cmdr. Jaruwan Changmool and Maj. Thanapon Yooman, who were expelled for serious offenses described in the Royal Gazette on Monday.

A royal statement said Jaruwan was slacking in her duties.

“[She] did not develop herself, lacked enthusiasm; was idle, and lacked correct judgment which caused damage” to His Majesty’s household, the Royal Gazette said in its proclamation stripping her of her rank.

Another statement accused Thanapon of multiple offenses, including disobeying orders from His Majesty the King himself.

“[He] used inappropriate words and behavior; disputed royal commands; displayed arrogance, insolence and insubordination; committed gravely evil acts; behaved carelessly in his bureaucratic duties; procrastinated; and neglected his bureaucratic duties,” the statement said.

Four other officers were stripped of their rank on technical grounds. The Royal Gazette said they had recently moved up two ranks within six months, which is not allowed under military regulations.

On the same day, His Majesty the King also promoted five members of his household corps, including three air force officers and two colonels, to generals, citing excellence in their services.

Meanwhile, 19 officials were fired from the Office of His Majesty’s Principal Private Secretary. Four of them held the rank of deputy director to the royal household, a title known formally as grand chamberlain.

The Royal Gazette did not say why the officials were expelled.
