No illegal migrant will ever get to stay in the UK of GB. By the very act of trying to enter the country illegally they have already committed a criminal offense so they are then criminals themselves, and we do not want foreign criminals in the UK of GB.
This is obviously completely at odds with the current policies of our politicans, who are hell-bent on getting as many illegal migrants into British towns and cities as possible creating ghettos and no-go areas for British people..
