Blyth Valley’s Ronnie Campbell claims the new ‘bedroom tax’, due to take effect from April next year, will hit the most vulnerable and those suffering from bereavement.
“This is yet another anti-working class tax on working class people,” said the MP.
If two or more are spare, she will lose £19.27 or a quarter of her weekly benefit.
The alternative, the MP said the resident had been informed, was to either move home, pay the shortfall herself or take in an approved lodger.
Mr Campbell blamed the changes on the welfare reform legislation passed by the government earlier this year.
“It is another big thank you to the Liberal Democrats,” he added. “The Tories have pushed this through with the Lib Dems.”
