PrinceDipangkorn Rasmijoti (Thai: ทีปังกรรัศมีโชติ; RTGS: Thipangkon Ratsamichot, pronounced[tʰīː.pāŋ.kɔ̄ːnrát.sà.mǐː.tɕʰôːt]; born 29 April 2005) is a member of Thailand’s Chakri dynasty and heir presumptive to the throne of Thailand. He is the fifth son and seventh and youngest child of King Vajiralongkorn; his mother is Srirasmi Suwadee, the king's third legal wife. His father also has a daughter by his first wife, and five children (four sons and a daughter) by his second wife; all the children of the second wife were born before the then-Crown Prince married their mother but were legitimised by their marriage. After the Crown Prince divorced his second wife in 1996, he disowned their four sons, leaving Dipangkorn as the only son recognised by the king.[1] He is rumoured to have a developmental disorder.[2][3]
The prince is styled His Royal Highness. A royal ceremony, called Phra Ratchaphithi Somphot Duean Lae Khuen Phra U (พระราชพิธีสมโภชเดือนและขึ้นพระอู่), to celebrate the prince's first month was held on 17 June 2005 at Ananta Samakhom Throne Hall in Bangkok.
Prince Dipangkorn is the heir presumptive to his father and first in line to the throne as the only officially recognised son of King Vajiralongkorn.[6] However, because of Vajiralongkorn's December 2014 divorce from Srirasmi Suwadee, Dipangkorn's position in the line of succession is uncertain. The 1924 Palace Law of Succession lists "the order in the line of succession", following the first-born son of the king to be "the first-born son of the said prince and his royal consort" followed by "younger sons, in order, of the said prince and his royal consort." When Vajiralongkorn ended his relationship with his second wife in 1996, he disowned their four sons and said they had renounced their royal titles. However, the Royal Palace continued to recognize their right to use the style HSH, or His Serene Highness.[7]
Prince Dipangkorn's position is also uncertain because a 1974 constitutional amendment allows princesses to succeed the throne in the absence of an appointed successor. Princess Bajrakitiyabha, the second presumptive heir in line to the throne based on the 1924 Palace Law of Succession and eldest daughter of the king, was widely thought to be the next person in line until falling into a coma in December 2022.[8][9]
