Mr Balls accused the Chancellor of taking a huge “gamble” on raking in cash from the 45p rate, higher stamp duty, closing tax loopholes and limiting tax reliefs. Attacking the “millionaire’s Budget”, Mr Balls said: “He’s hit pensioners but given to 300,000 people on incomes above £150,000 a £3 billion tax cut.... an average cut of £10,000.” Mr Osborne’s aides insisted his assumptions were backed by the independent Office for Budget Responsibility.
