Is it possible to stop illegal immigration?
Throughout this week Newsnight has been dealing with the issue of illegal immigration in Britain. Independent journalist Sorious Samura has produced three fascinating reports on the subject, involving undercover filming to test the boundaries of the British immigration system.
The series concludes this evening with a look at how easy it is for some illegal immigrants to obtain false documents which allow them to work in the UK.
You can watch the first two films online and we'll be discussing the issues all three films raise in tonight's programme, including the main question - is it actually possible to stop illegal immigration into the UK?
Let us know your views on the issue.
