According to RadarOnline.com, Charles, 76, has grown increasingly frustrated with Andrew and Ferguson's refusal to vacate the 30-room residence despite years of pressure. The cancer-stricken King now sees eviction as necessary "to preserve the integrity of the monarchy," a senior royal source said. "It has convinced the king that there is no route back for Sarah in terms of public life, and that Andrew cannot be shielded either." Andrew has resisted efforts to move him out of the estimated $40 million Royal Lodge, citing a long-term lease with the Crown Estate. Since Queen Elizabeth's death, Charles has allowed Ferguson back into the royal fold, including appearances at Sandringham and Windsor Castle during major holidays.
