Government policy is not to build new grammars, and that is also the policy of Her Majesty's Opposition, which is truly curious, as the Tory party have always been the "party of the Grammar School".
Oh no they haven't.
My Grammar was closed by the Tories (both government & county). I think Mrs Thatcher was education secretary at the time - they didn't like the idea of the lower classes getting an appropriate education. Which was why Labour supported grammars!
So it's Labour who have changed their views, not the tories.
