Two-thirds of those hit by bedroom tax are behind with rent
Two-thirds of households hit by the bedroom tax are in rent arrears.
The shock findings of the National Housing Federation (NHF), which represents the UK's housing associations, show that more than a third had fallen into debt because of the charge.
It used polling firm Ipsos-Mori to survey 183 associations, and the firm found that thousands could simply not cope with the change.
The bedroom tax takes an average of £14 per week from the benefits of those with a bedroom they don't use, and £25 from those with two.
