Imagine that you are an Afghan who, despite having worked with the British, has not made it on to the very limited resettlement programmes and is now one of the many Afghans risking their lives in a small boat in desperation to escape the Taliban.
On arrival you are declared illegal, put into detention and then deported and banned from ever entering the country again, without any opportunity to make your case for asylum.
This is the intention of the so-called Illegal Immigration Bill.
