About one third of the £594m earmarked for tutoring to help children catch up after Covid lockdowns has gone unspent, a BBC investigation has found.
The government's National Tutoring Programme (NTP) offers one-to-one or group lessons outside of school hours.
Schools must top up any government money from their own budgets, something some teachers say they cannot afford.
The government said it had helped millions of children - but Labour called the scheme a "shocking failure".
Almost £209m of the £594.3m allocated to the NTP for the previous two academic years has not been spent, according to a BBC Freedom of Information request.
