My right hon. Friend makes a good point.
We need to send signals to people around the world that we are serious about ensuring that people who are here illegally should not stay. That is why I welcome the measures on bank accounts and driving licences. There are concerns about private sector landlords, but if someone is about to rent out a £250,000 or £500,000 home, there is a good, solid logical reason for having the full documentation. After all, they want to collect the rent. Many residential landlords already take passport and other such details. The Bill is a perfectly common-sense approach to ensuring that there is a barrier for those who should not be here but no difficulty for those who have a right to be here.
