A quarter of Britain’s richest families are weighing up leaving the country as fears mount over Labour’s tax raid on private schools and speculation of further levies in next month’s Budget.

The backlash against Labour’s decision to impose VAT on private school fees has been particularly fierce. A quarter have cut pension contributions, while a third paid school fees in advance before VAT was applied.
