Child Poverty Bill

The noble Lord has made this point before. I understand perfectly well that, when two people share a household in that way, some benefits relate to the household and some benefits may be individual. The noble Lord says that there is a penalty when two people come together, because the total benefit is reduced compared with the two single benefits. How, then, would he assess housing benefit? If that couple subsequently broke up, would they really receive half of what they had been receiving, even though they had to go on to form two separate households instead of one?
