There an awful lot of issues in all this. Today Germany is considering removing free legal advice from its illegals. That might be wise here too. It could also help speed up the process. With Climate change we are in a whole new world on the planet on these issues and I would change international law.
We have 1.1m last yera and 1.3m year before new peopole coming here. I would like that to be about zero -samd as first 30 years of mky life (that is lawful immigration - our biggest issue). Then we have about 1m illegals already here, 600k of them in London (estimate).- we removed 19,000 only last year. We need to remove more like 250,000 a year.
Separately we have vast numbers of visa over stayers - the biggest number of illegals who rarely are removed. Finally we have those in hotels and even worse HMOs when we should deal with claims within about 7 days and house them in new places - we bought in 12 days Nightingale hospitals in the pandemic as Susan Hall said the other week; so surely we can build places for people for their 7 days and then remove them.
People who say walking by a hotel is fine have no idea what mass huge numbers of new people from cultures that treat women as property mean. Even just going into our local tube station is like being exported to Teheran at times just in terms of the large groups of men, the way they look at women in a way even white van men don't in the UK and much else. It is a whole new world when you become the minority in your own land and when the new people do not adopt your culture.
Democracy works. if the state does not deal with all of this the people will vote accordingly.
