Commenting ahead of Justine Greening's speech on working families and the education system, Leader of the Liberal Democrats Tim Farron, said: "The government are fiddling the figures, pure and simple to make their case for a discredited grammar schools plan."
"This shows the Conservatives' true colours, while schools struggle to pay for books, cut teachers and buildings decay around them the government have found more cash to pay for Grammar Schools.
"What's worse than that pupils of working families are getting stuffed by this plan, yet again. Rather than making every state school excellent the government want to spend more cash on another ideological experiment.
"This speech is the political equivalent of a rose tinted view of the 1950’s where a few excel and millions of other young people are consigned to the scrapheap."
