Protesters are due to march in Cardiff today against the so-called 'bedroom tax'.
The Department of Work and Pensions say the removal of the bedroom tax is a "necessary reform" and that it has made money available to help local authorities in Wales "support vulnerable people".

The removal of the spare room subsidy is a necessary reform to return fairness to housing benefit. Even after the reform we pay over 80% of most claimants' housing benefit - but the taxpayer can no longer afford to pay for people to live in properties larger than they need. It is right that people contribute to these costs, just as private renters do.
To help with the transition we have made £6.2m available to Welsh councils to support vulnerable people, with an additional £880,000 available to help those in rural parts of Wales.
Hundreds of protesters will march through Cardiff against the 'bedroom tax'.
Homeless charities, the Church in Wales and assembly members have all spoken out against the controversial plans to charge tenants for empty bedrooms.
Shelter Cymru say they have seen an increase in tenants falling behind in rent payments due to the 'bedroom tax'.
They have also called on the Welsh Government to increase the one and two bedroom housing stock.
A Department for Work and Pensions spokesperson said:
"The removal of the spare room subsidy is a necessary reform to return fairness to housing benefit...the taxpayer can no longer afford to pay for people to live in properties larger than they need."
