The immigration problem in the UK is not something which does not have a solution.  What it needs is a determination and a leadership with a strong spine to save the country from untoward future headaches.  To make room for the new arrivals, the UK government has to clean its house first which means to deport all, I mean all, illegal residing in the country.  Secondly, anyone, I mean anyone, who is preaching anti-UK sermons ought to be declared a traitor and should be shipped out without wasting too much time.  If that person is UK born, he ought to be locked up for a longer time, without parole.  The UK government ought to be very selective in issuing visas.  These visas should be issued only to those who are well qualified to contribute positively further to the economic and technological development of UK.  This might require a constitutional amendment, so be it.  If the existing tenets of constitution is not working in favor of a country for which the constitution was written, it needs to be changed with the changing times - otherwise it will remain as a piece of paper with no values.  THE UK GOVERNMENT NEEDS TO BE PROACTIVE IN THIS MATTER TO SAVE THE FABRIC OF A COUNTRY.
