Sir: The number of exam boards in England has been cut from 24 to four since the introduction of the GCSE examination ("Exam boards face streamlining", 28 August). Further reductions would eliminate choice completely - especially if the logic of Gillian Shephard's argument is extended to universities. With only one, we could be sure that everyone sits exactly the same examination nationally, having all taken exactly the same course.
And with one newspaper, we could be sure of consistency in the news we receive. A national water board, railway or airline would guarantee consistency too. Whether or not it would be consistently good is a different matter.
