The reason the Government's troubled families programme works is because it is "fixing the services around the families as much as we're fixing the families," the head of the scheme told Good Morning Britain.
Louise Casey, director general of Troubled Families, said too often families' problems have been looked at separately, which "isn't going to solve anything."
Eric Pickles has announced a major extension of the programme - it has reached 120,000 families so far, and will now target over half a million.
These families have an average of nine significant problems; truancy, domestic violence and debt are just some of the wider set of issues the expanded scheme will tackle.
