Thailand’s King has made his mistress a royal consort in a ceremony attended by his new wife, marking the first time the country’s modern monarchy has publicly admitted to polygamy. King Maha Vajiralongkorn, also known as Rama X, made his former bodyguard Sineenat Wongvajirapakdi, 34, his chao khun phra (royal noble consort) in a ceremony on his 67th birthday.
