Thailand’s King Maha Vajiralongkorn has stripped his 34-year-old consort of all titles for “disloyalty” and apparent “ambition” to match the Queen’s position, a royal command issued late on Monday said, less than three months after she was bestowed with the honour.

Former royal bodyguard Sineenat Wongvajirapakdi – known by her nickname “Koi” – was gifted the title on the king’s 67th birthday on July 28, the first time in nearly a century a Thai monarch has taken a consort.

A few days later the palace released images of the short-haired Sineenat in combat fatigues shooting weapons, flying a jet and preparing to parachute from a plane, as well as holding the king’s hand.

It was an intimate and rare glimpse into the private life of Thailand’s powerful, ultra-wealthy and inscrutable monarch, known as Rama X of the Chakri dynasty.

But on Monday Sineenat’s swift and public downfall was relayed on national television.

She was dismissed from the rank of Chao Khun Phra – or noble consort – for “disloyalty to the king” according to the command, as well as “acting against the appointment of the Queen (Suthida)… for her own ambitions”.

Suthida – the former deputy head of the royal bodyguard – was made Queen in May, becoming King Vajiralongkorn’s fourth wife.

Koi, a qualified pilot and former army nurse, was the first woman to receive the consort title in nearly a century – fitting a pattern of assertive moves by the king. (AFP)
