"A couple who care for their severely disabled grandchild have lost an appeal against cuts to their housing benefits because they have a spare bedroom.
Susan and Paul Rutherford, of Pembrokeshire, argued the room was essential because it is used by carers who look after Warren, 14, overnight.
They claimed the £14 a week reduction to their benefits, described by critics as the "bedroom tax", was unlawful.
But a High Court judge dismissed their judicial review claim.
