The leader of North Korea, Kim Jong-un, has wiped his hated step-grandmother's mansion off the map, amid speculation that he's too broke to maintain her royal residence, reports The Daily Mail. After the death of the dictator's grandmother, his grandfather and predecessor, Kim Il-sung, remarried and started another family. But relations between the rival royal lines were fraught, with the new wife, Kim Song-ae, accused of trying to install her own son on the throne. So Kim Jong-il, the current leader's father, had her placed under house arrest, and her son, Kim Pyong-il, was sent into exile as a career diplomat. But Kim Jong-il could not harm his stepmother, and after the death of her husband in 1994, she was allowed to live out her days in a mansion. The aforesaid house “sat on a small hill next to an artificial lake on the Hapjang River, surrounded by 11 hectares of woodland. It was also protected by a security fence and had its own on-site facilities for guards and other workers," said North Korea expert Jacob Bogle. Now satellite photos have revealed that Kim Jong-un has bulldozed his step-grandmother's home, leaving no visible trace of it after her death.
