Brian's comments may well have some basis in that we English have elected a series of governments which have perpetuated policies with which he disagrees, but I do take exception to his use of the word "miscreants" to describe the immigrants to the UK. The vast majority are people who come to look for work and usually find it.
The great Enoch when he was Health Minister, encouraged a large number of Commonwealth immigrants into the understaffed National Health Service. Powell was vehemently opposed by the Trade Union movement (who feared that immigrants were being used by capitalists to keep wages low by artificially increasing competition for jobs).
Now that sounds familiar in Cameron's Britain.
Enoch Powell was a complex character, but seemed to derive his political thinking from his studies of classical authors - often resulting in ideas which were fine for the Roman Empire, but too simplistic for the 20th century.
Powell was not reticent about migrating himself to find work, though admittedly Australia is pretty British.
He had early ambitions to be Vice Roy of India - a vast country of largely black people to be ruled over by a white minority. He also wanted to scrap Britain's nuclear weapons. He was implacably opposed to the EEC (or EU nowadays). He urged people to vote Labour in order to punish Ted Heath. He was very anti-American. In short he seems to have been an opportunist whose own ambitions were thwarted by his cussedness.
Brian also asks "why are so many people leaving Britain?" How many of them were immigrants in the first place? He paints a picture of Brits fleeing to other places where there are no foreigners and being replaced by Afghans and Syrians, or Bulgarians, Poles etc.
In 1066 the previous immigrant waves of Anglo Saxons and Vikings was followed by Normans from France, all of whom threatened to engulf the previous lot. But they grew to like the place and make it what it became, a powerhouse of culture and liberal prosperity. Long may it continue.
