PHNOM PENH: Former Thai Prime Minister Thaksin Shinawatra and his sister, former PM Yingluck Shinawatra, were seen attending outgoing Prime Minister Hun Sen’s 71st birthday celebration over the weekend.

Prime Minister Hun Sen’s Tiktok account posted a video on August 6 from his birthday celebration held the previous day. In it, Thaksin and Yingluck can be seen standing next to the Cambodian Prime Minister and his family. The Prime Minister wrote on the post that they are "brothers from another mother.”

Thaksin was ousted by a military coup in 2006 and Yingluck was found guilty of dereliction of duties by the same military junta in 2017. Both have been living in self-exile to avoid jail sentences handed down in what they say are politically motivated court cases. Thaksin recently announced that he would return to Thailand after national elections in May saw the military lose. However, the date of his return to the country is still unclear, as it has been postponed due to what he says is a medical appointment, while the Thai parliament is deadlocked on a decision about the country’s next prime minister.
