Is this part of the hostile environment?
As I read it if you are an asylum seeker and don't respond to the Home Office, the Home Office then just shrug and let you stay in the UK.
Now if you are an asylum seeker and want to regularise your status in the UK this is a problem.
If on the other hand you are an economic migrant (also known as a slave) this plays right into your (your slavemasters) hands. You can stay in the UK.
Given the belief of some that most asylum seekers are economic migrants this does not seem entirely what they may thinking of when it comes to Stop the Boats.
I must bookmark the link for the next time there is an ill informed discussion.
