For several decades, the UK sent children across the world to new lives in institutions where many were abused and used as forced labour. It happened to thousands of British children ... following World War Two. The astonishing scandal of the British child migrants will be the first subject for which the Independent Inquiry into Child Sexual Abuse will hold full public hearings. It's first because the migrants are now nearing the end of their lives. Sources close to the current public inquiry have told the BBC it will produce new and startling revelations about the scale of sexual abuse abroad, and attempts by British and Australian institutions to cover it up. This will include an examination of the claims of some child migrants that they were sent abroad weeks after reporting sexual abuse at their children's home in the UK. The allegation is that they were hand-picked. Either to get them out of the way, or because they were of interest to paedophiles. Three former Fairbridge boys have claimed that the then-Australian Governor General, Lord Slim, sexually molested them during rides in his chauffeur-driven Rolls Royce while visiting the home. It is understood these allegations could be considered by the inquiry. The inquiry could also definitively answer a crucial historical question. Did the British government know it was sending children to be mistreated in a foreign country?
