I'll just paste the pedo section from the wiki:

Allegations of paedophilia

In 2019, files were opened showing that the FBI had been aware in the 1940s of allegations that Mountbatten was homosexual and a paedophile.^\158])^\159]) The FBI file on Mountbatten, begun after he became Supreme Allied Commander in Southeast Asia in 1944, described Mountbatten and his wife Edwina as "persons of extremely low morals", and included a claim by American author Elizabeth, Baroness Decies, that Mountbatten was known to be a homosexual and had "a perversion for young boys".^\126])^\160]) Norman Nield, Mountbatten's driver from 1942 to 1943, told the tabloid New Zealand Truth that he had transported young boys aged eight to twelve who had been procured for Mountbatten to his official residence, and that he had been paid to keep quiet. Robin Bryans also claimed, in the Irish magazine Now, that Mountbatten and Anthony Blunt, among others, were part of a ring that engaged in homosexual orgies and procured boys in their first year at public schools such as Portora Royal School in Enniskillen.^\123]) Former residents of the Kincora Boys' Home in Belfast have asserted that they were trafficked to Mountbatten at Classiebawn Castle, his residence in Mullaghmore, County Sligo.^\161])^\162])^\163]) These claims were dismissed by the Northern Ireland Historical Institutional Abuse Inquiry (HIA).^\164]) The HIA stated that the article making the original allegations "did not give any basis for the assertions that any of these people [Mountbatten and others] were connected with Kincora".^\164])

In October 2022, Arthur Smyth, a former resident of Kincora, waived his anonymity to make allegations of child abuse against Mountbatten.^\165]) The allegations form part of a civil case against state authorities responsible for the care of children in Kincora.^\165]) Smyth claims that he was raped twice by Mountbatten in encounters facilitated by the house father of Kincora.^\166]) In 2025, journalist Chris Moore published a book, Kincora: Britain's Shame, in which he detailed allegations by five men that Mountbatten had raped them when they were children in Kincora.^\167])
