Children in care have reported being groomed and sexually assaulted in homes run by a firm making huge profits.
Multiple employees of Calcot Services for Children say vulnerable young people were failed.
BBC News has found it made profits of 36% last year, double that of other big care providers - figures already considered excessive by a watchdog.
Calcot said profits were high because of built up investment, and it prioritises safeguarding children.
The company runs eight homes, four schools and supported living accommodation in southern England. It made profits of 42% in 2020 and 36% in 2021, using an industry-standard measure.
