Immigration is not the major problem. The problems lie in the fact that Govt. use immigration to cut back on nurse and doctor training in the Uk by poaching nurses and other health care workers from overseas. Same applies to apprenticeships for plumbers, carpenters and other trades - the Govt. slashes apprenticeships ( The type where the young person is indentured for four years) in favour of poaching overseas tradesmen. Now we have a shortage of both and Boris thinks he can suddenly supply 5000 Doctors who will be trained in the UK. He forgets it takes some years to train doctors and tradesmen. But he probably knows but he promises great things and delivers little. He was taught rhetoric at Eton -how to sound good and be persuasive but forgets he has to deliver or people might suspect he is all piss and wind.
