Blyth Valley MP Ronnie Campbell has voted against the controversial ‘bedroom tax’.
He said the tax has created problems for thousands of people across the country, costing some families an average of £700 a year.
Opponents of the initiative say two thirds hit by the tax have disabilities while 60,000 are carers. In the north east, nearly 37,000 people have been affected.
The issue was raised in a Parliament debate last week, and although the vote was approved by Labour MPs, it has not seen the end of the tax.
Mr Campbell said: “David Cameron and Nick Clegg’s cruel and unfair bedroom tax has hit the poorest and most vulnerable in our community.
“Despite the clear evidence that the tax is causing misery, hardship and forcing thousands to rely on food banks, the Lib Dems and Tories have voted again and again in favour of it.”
