The KingThe QueenChaokhun Phra Sineenatha Bilasakalyani The Queen Mother Prince Dipangkorn Rasmijoti (Thai: ทีปังกรรัศมีโชติ; RTGS: Thipangkon Ratsamichot, pronounced [tʰīː.pāŋ.kɔ̄ːn rát.sà.mǐː.tɕʰôːt]; born 29 April 2005) is a member of Thailand’s Chakri dynasty and heir presumptive to the throne of Thailand.

[2][3] Prince Dipangkorn Rasmijoti was born by Caesarean section on 29 April 2005 at Siriraj Hospital in Bangkok.

[5] 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.

[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.
