Immigration and Social Security Co-ordination (EU Withdrawal) Bill

My hon. Friend is drawing attention to a very important issue. Does he agree that the crucial point is that a local authority may have the statutory duty as the corporate parent, but if the child does not have documentary evidence proving their nationality—not their residence, which the local authority can prove easily, but their nationality—the local authority is unable to take forward the application at all? I hope the Minister will be able to address that issue when he responds to the debate.
