[2] To avoid political conflicts with Lady Si Suda Chan, Prince Thianracha (พระเฑียรราชา), the most senior member of the royal household, became a monk and stayed at Ratchapraditsathan Temple (วัดราชประดิษฐาน) throughout the reign of Yotfa.

[2] Jeremias van Vliet recorded that Yotfa was fond of riding a horse along the fields, watching elephant duels, learning to use weapons and studying political science, and that his reign saw abundance of agricultural products.

Lady Si Suda Chan eventually summoned all government officers and told the meeting that Yotfa was too young to rule the kingdom and that "I will place Khun Worawongsathirat in charge of public administration until my son is mature enough".

[2] The Astrological Annals recorded that the execution was held on Sunday, the fifth day of the waxing moon in the eighth month of the 910th year of the Minor Era, corresponding to 10 June 1548.

[3] Lady Si Suda Chan, as well as her paramour and newborn daughter, were later killed in a countercoup staged by senior government officers, led by Khun Phirenthrathep (ขุนพิเรนทรเทพ).
