I was interested in knowing whether the Minister had evidence on whether their warrant to arrest sanction is working. Because I know when I've asked this question, she's pointed me out to the Welfare Expert Advisory Group (WEAG) report evidence review paper, but the warrant to arrest sanction is not mentioned once in that paper. So does the Minister hold any evidence that the sanction is working, because the previous Government didn't have evidence on Section 70A of the Social Security Act 1964, on sanctions for sole mothers. So I'm concerned that we are continuing down a path of putting a sanction on families where there is no evidence that it works.
