Michael Gove has expressed his sympathy for students over the GCSE grading row but said he would not take responsibility for decisions made before he became the Education Secretary.
Gove said that it is the past government's fault for problems leading up to what has happened - for example, modularisation.
He added that he did not believe OFQUAL could have known that English gradings in January were over generous compared to June as the sample was too small.
Gove said he was ready to acknowledge mistakes that may have happened with OFQUAL, if he is presented with evidence to prove it.
Ofqual denied applying pressure to exam boards to change their grades, saying it was merely playing its proper role in regulating standards.
Schools alliance have announced they have formed an alliance to demand an independent inquiry into the GCSE English grading fiasco.
Exams regulator, Ofqual is to look again at some GCSE English results amid claims that thousands of students have been treated unfairly.
