Nick Clegg, deputy prime minister, offers reassurance that he does not support a profit motive within the school system:
"To anyone who worried that, by expanding the mix of providers in our education system, we are inching towards inserting the profit motive into our school system, again, let me reassure you.
"Yes to greater diversity; yes to more choice for parents. But no to running schools for profit, not in our state-funded education sector.
"They must not be the preserve of the privileged few - creaming off the best pupils while leaving the rest to fend for themselves, causing problems for and draining resources from other nearby schools.
"So let me give you my reassurance - I would never tolerate that."
