BANGKOK, Nov. 30 (Xinhua) -- Thailand's Crown Prince Maha Vajiralongkorn had already "informally" accepted to ascend to the throne as King Rama X, said Deputy Prime Minister Prawit Wongsuwan on Wednesday.

"(The Crown Prince) was known to have already accepted the invitation to become king. Everything has been done in accordance with the established procedures," Prawit told reporters on Wednesday morning.

Thai parliament, or National Legislative Assembly (NLA), formally invited the prince to ascend to the throne on Tuesday.

Once the prince formally accepts the invitation from the parliament, the prince will be proclaimed King Rama X of the 234-year old Chakri Dynasty, succeeding his father, late King Bhumibol Adulyadej, who had ruled for 70 years and passed away at the age of 88 last month.
