Borders, Citizenship and Immigration Bill [HL]

My Lords, I rise to support the noble Lord, Lord Avebury, and—I beg your Lordships’ pardon—to speak briefly to another matter related to Clause 53, which is the keeping of statistics. I know that the amendment has been withdrawn, but will the Minister write to the Science and Technology Committee of the House of Lords, setting out the debate on statistics, and take its advice on the most effective way of keeping statistics on children held in detention? We should look particularly at longitudinal statistics, because they provide a richer and better understanding of what is going on, allowing us to discuss more than snapshots. There may be an argument for undertaking a longitudinal study on a limited group in Yarl’s Wood.
