In a debate on the Finance Bill, Sefton Central Labour MP Bill Esterson slammed the Tory-Lib Dem Government for hitting ordinary families the hardest with unfair cuts.
During the debate, Bill challenged government minister Justine Greening on the cuts to families with children of the budget.
Bill said: "The House of Commons Library calculate that families will be up to £1,700 per year worse off as a result of cuts made by the government in the budget. The Chartered Institute of Taxation say that withdrawing tax credits and child benefit from middle-income households will result in them being squeezed more than those on high incomes.
"It is clear that the government is clobbering the poorest families and those on middle incomes the hardest, while letting high earners pay relatively little.
"This cannot be fair and it cannot be the right way to pay off the deficit. Those earning most should make the biggest contribution. That's a sensible and fair way of running the country.
“The government could start by taxing bankers bonuses and using that money to support jobs and the economy rather than hitting those on low and middle incomes and cutting from those who can least afford to pay.
"Those families who are on low and middle incomes are being hit hardest by the Conservatives and Liberal Democrats and that cannot be either fair or a sensible way of helping either families or the economy in such tough times."
