Single-sex schools go co-ed under economic pressure ("Is it all over for boys' schools?", TES Magazine, 27 May). The best schools in the UK market are still boys or girls only - Eton, Winchester, The Oratory, St Mary's Ascot, Cheltenham Ladies, etc - and they have strengthened their position at the top. All heads know that this is the "elephant in the room": take girls or boys to survive, and then make an argument for co-ed as "the modern way forward".
