Another blue-blood who has made public her views is Malinee Chakrabandhu, a descendant of King Rama IV, who ruled Siam in the 19th century. She posted a photograph of herself wearing a T-shirt that read: "I support the Crown Prince."
In an interview at her tastefully-decorated home where photographs of her with other royals - including Britain’s Prince Charles - adorn the walls, Ms Chakrabandhu denied being a "signed-up" supporter of the government.
But she said she opposed the anti-government protesters and had fallen out with several family members over the issue, including her daughter.
"I back the Crown Prince. Nobody else. He is next in line and we have no right to change that."
The 66-year-old Ms Malinee, who uses the title Mom Rajawongse, or MR, a signifier of her royal heritage, said: "Most Reds also support the Crown Prince. But most MRs are yellow [anti-government] and that disappoints me very much."
The current stand-off in Thailand is not only about the succession issue. Among the protesters who have seized control of parts of Bangkok are farmers, particularly from the south, and middle-class citizens who believe Mr Thaksin oversaw widespread corruption. They are angry over an amnesty bill that would have allowed him to return to Thailand.
The leadership of the protesters has claimed there is no-one pushing them to act or funding them. "We are not claiming we have the support of the royals. This has nothing to do with the monarchy," said Akanat Promphan, a spokesman for the protesters.
