The Inquiry was set up to investigate the abuse of children in care in Scotland.

A statement on behalf of the Ponton Trust was given at the opening of the inquiry’s latest phase in January.
It said: “The trustees of the Ponton Trust unequivocally condemn and abhor any such abuse and offer an apology to any young person who was subjected to abuse while residing at the Ponton House Boys’ Residence.”
