Teachers helped a 15-year-old pupil to have an abortion that her parents knew nothing about.
Her mother and father finally learned about the termination when she told them after it had happened.
Last night family campaigners said the case showed how parents are increasingly being sidelined by the law.
It is understood that the girl went to a hospital where it was confirmed she was pregnant. In line with her wishes, doctors did not tell her parents but notified the school in Salford, Greater Manchester, instead.
Teachers discussed the termination with the girl, checking she was comfortable with her decision. They also gave her time off school and supported her when she went for the procedure.
