Ed Balls will criticise the Conservatives for cutting taxes "at the top" and doing nothing to help those on low incomes increase their wealth.
In a speech given in Bedford, Mr Balls will say:
We know the Tories' real economic plan - it's to cut taxes at the top and hope that wealth will just trickle down.
Having already cut taxes for millionaires in this Parliament, they're champing at the bit to do it again if they win the election - cutting the top rate of tax for people earning over £150,000 again from 45p to 40p. Another tax cut worth £3 billion for the richest 1% of our country.
