In upholding our immigration rules, we seek to assist those who have no right to be here to return home, whether on a voluntary basis or indeed, on occasion, by force. It is really important that we have an immigration system that is robust. We do not have indefinite detention. The hon. Lady will have heard me say that 92% of those held are released within four months and 63% are released within a month. It is important that we have a system where we can be confident that when we are able move people to removal, we have the capacity to do so.
