Private schools are set to be charged up to three times more for an Ofsted inspection in Labour's latest raid of the independent sector.

Education Secretary Bridget Phillipson will take an axe to the discount private institutions currently enjoy for visits by the schools watchdog.

Two thirds of the inspection costs are currently subsidised by Ofsted, who visit around half of England's 2,496 registered private schools every year.

But this will be swiftly removed by Ms Phillipson this week, in an announcement which will arrive less than a year after Labour dramatically hiked VAT on private schools.

Since the tax raid on schools last year, more than 50 institutions across England have signalled their intent to close.
