Or to put it bluntly better quality better paying jobs will be reduced, while poorer quality and poorer paying jobs will have to be covered by UK workers or do without. While there still may be shortages in some key skilled areas because there isn't enough British Skilled workers and some moving to better opportunities abroad. A comment from a friend visiting from Canada recently, some tradespeople very difficult to get in Canada not many Polish Plumbers there. Of course in reality any deal with the EU will still likely have a certain level of immigration from EU countries, and other non EU countries are already talking about linking trade deals to immigration. So anybody who thinks that there will be hardly immigration after brexit is in cloud cuckoo land which is essentially why I voted to stay in. Governments never control immigration to the level many of the population want. The Labour party particularly Corbyn don't seem to believe in immigration Controls while the Tories know that a certain level of immigration is required for skills shortages and a good pool of cheap Labour.
