James Kempton, a leading member of London Councils, said: "All London's children deserve to enjoy the very best education and school facilities we can offer. Temporary classrooms and expanded classes are simply not good enough, but London's boroughs are being forced into a position where these are our only option to provide places for the capital's five-year-olds. We urgently need the Government to bring forward emergency funding to cover the current and expected demand for places. London's children deserve better."
