Building work on hundreds of schools may have to be abandoned if the government is to fully implement its "free schools" policy, the Institute for Fiscal Studies (IFS) has said.

It said there was not enough money both to finish Labour's £55bn school renewal programme and fund free schools.

The government says free schools will improve the quality of education.

But shadow education secretary Ed Balls said cancelling Labour's building plans would "set back education".

The government's free schools policy encourages parents' groups, trusts, charities and other providers to set up their own schools. - bbc
