Brown's time as Chancellor was marked by major reform of Britain's financial and fiscal policy architecture. For example, was the interest rate setting power transferred to the Bank of England. This was done by a wide extension of the powers of the Treasury to cover much domestic policy and by giving the responsibility for banking supervision to the Financial Services Authority. Controversial moves included the abolition of Advance Corporation Tax (ACT) relief in his first budget, and the removal in his final budget of the 10 per cent "starting rate" of personal income tax which he had introduced in 1999.
