A coalition of housing charities, church and campaign organizations have joined forces against the bedroom tax.
Cardiff & South Wales Against the Bedroom Tax, which unites Shelter Cymru, Welsh Tenants, TPAS Cymru and the Church in Wales, has started an online petition urging the Welsh Government to subsidise the tax.
Best estimates indicate the operation would cost Welsh taxpayers around £17 million.
The coalition says they are aware of the budgetary challenges posed by central government cuts, but believe that mitigating the tax is necessary.
Campaign co-ordinator Jamie Insole says, “The tax is not just hitting vulnerable groups like single parents, disabled and mentally ill. More than that, it is creating vulnerability.”
The petition is open until 8 February 2016.
