Acting Supreme Patriarch

Somdet Kiaw was appointed acting Supreme Patriarch in 2005 due to the failing health of the incumbent Supreme Patriarch Nyanasamvara Suvaddhana. He was a monk of the Mahanikaya order, and was of Thai Chinese descent. His appointment provoked severe criticism from Luang Ta Maha Bua (of the Dhammayuttika Nikaya order) and Sondhi Limthongkul, who claimed that the appointment created two Supreme Patriarchs and contravened the royal prerogative of King Bhumibol Adulyadej. On 4 March 2005, Maha Bua even petitioned King Bhumibol Adulyadej to remove all of Kiaw's royal titles.
