Twigg: GCSE marking 'must be fair', says Labour
There has been a fall in the proportion of GCSEs awarded an A*-C grade, for the first time since the exams were introduced 24 years ago.
This year's results show 69.4% of entries earned grades A*-C, compared with 69.8% last year.
Shadow Education Secretary, Stephen Twigg, told BBC News that while there was a case for reforming the GCSE system, a return to O-Levels was not the answer.
