David Cameron has for some reason decided that the pressure on single parents isn't enough. I have no problem with him chasing up runaway parents (mostly Dads) for maintenance money. Forcing people who don't want to do so to spend time with children however doesn't strike me as a sensible plan and his focus on the importance of marriage above all else in child-raising offers little encouragement for the 1 in 4 women in this country who will be a victim of domestic violence in their lifetime.
His big piece of data is that "70% of young offenders are from lone-parent families". Well here's another piece of statistical data he seems to have overlooked: 80% of the benefits of a two-parent family come from the improved financial status. What single parents really need to enable them to raise their children well is quite often money.
