A spat between Singapore Prime Minister Lee Hsien Loong and his younger sister has blown into the open, one year after the death of their iron-handed father Lee Kuan Yew, who brooked no discord within the city-state's political world. Lee's sister accused the prime minister in a Facebook post of abusing his power and forming a political dynasty, a highly unusual public comment in Singapore. It has sparked an online debate in a country where the Lee family is mostly held in high regard and where several of its critics have been sued for defamation, according to Reuters. "I am deeply saddened by my sister Dr. Lee Wei Ling's claim that I have abused my power to commemorate the one-year anniversary of Mr Lee Kuan Yew's passing in order to establish a dynasty. The accusations are completely untrue," the prime minister said in a Facebook page on Sunday evening. It was not immediately clear why the younger Lee accused her brother of forming a political "dynasty" or why she went public with the criticism. There has been no suggestion that any of the prime minister's children would be keen to enter politics. (Source: Reuters)
