Selling school playing fields?

With the interest in sport and sports facilities at its highest as a result of the wonderful London Olympics, it is a shock to find that a school in a London Borough - Conservative Wandsworth -  has got permission from Michael Gove, Secretary of State for Education, to sell five acres of playing fields at Elliot School, Putney. He has approved  22 applications to sell school playing fields in England since 2010.  So much for Prime Minister David Cameron's most recent pronouncements!
