I hope that the hon. Lady will allow me to continue with what I have to say; these issues affect all of us in the capital. In his Budget statement, the Chancellor said that we could no longer have a state of affairs where people who do not work are living in homes that ordinary working people simply could not afford for themselves. Putting aside that principle, housing benefit has also become an enormous trap, as the hon. Member for Islington North rightly said, for its recipients in London, and I agree. In the past few weeks, I have canvassed people in the Churchill Gardens estate, where the precise situation that the hon. Gentleman described is prevalent. In other words, people are living next door to one another, one in a council property paying rent that is very low by the standards of the vicinity, and another in a property that has been sold two or three times and is now in the hands of a housing association, effectively being passed on to nominations from the local authority at three or four times the rent of the property next door.
