As I explained to her hon. Friend, I do not think it strikes a good balance because the children who live in families with lots of siblings are the children who live in poverty. I know that Conservative Members are not as committed to addressing child poverty as were the last Labour Government, and we will see the results of that as we go through this Parliament. I regret that. I am surprised that the hon. Lady, who is in general a practical, well-rooted person, does not see the power of that point.
Another issue is the fiddly definitions of partnerships and the difficulty that Ministers will have in establishing what those are for the purposes of the measure. The measure is both administratively fiddly and extraordinarily mean. It will affect more than 1 million families; about 1 million people are going to lose £1,300 a year. That is a significant sum and I wish that the Government would take more seriously both the practical and the fairness arguments that we are making.
The Minister has still not addressed one final issue: people who at the moment get national insurance credits by claiming child benefit. They will lose their national insurance credits, which will impact on their pension entitlements for many years to come.
I hope that the Minister, even at this last stage, will have a last-minute conversion.
