Under Thatcher these atrocities to British soveriegnty would never have happened. Under Thatcher it was a regular order of the day to deny entrance to England those that would undermine the British way of life. It seems that historic British stiff upper lip has given way to a trembling lower lip. This is what happens when a nation sells its independence for oil/investment dollars. All loans (Middle East Oil $$) come with come with fine print attached.
This isn’t the England Churchill led to victory in the Battle of Britain and the great WWII anymore.
Coming to America as fast as the Obama Administration can orchestrate it, look for this in our neighborhoods soon!
That, if I may say so, is to oversimplify patterns in recent British history which are rather more complex. Both of the main British political parties when in Government have at various times encouraged immigration, and at other times sought to limit immigration. Much of the intial wave of postwar immigration from 'New Commonwealth' countries took place under Conservative governments, who deliberately recruited cheap labour to help deal with labour shortages in the 1950s. Indeed it was Enoch Powell, now best remembered as an eloquent Cassandra warning of the dangers of uncontrolled immigration, who as Health Minister in a Conservative government brought in large numbers, particularly of Afro-Caribbeans, to staff the infant National Health Service. Conversely the first legislation to limit immigration, and to remove the automatic right of entry from British passport-holders in the former colonies, was introduced by the Callaghan Labour government of the 1970s.
As for Thatcher, immigration was not an issue which seems to have been very high on her agenda. As far as I know (subject to correction) she never made a major speech on the subject or introduced any radical policies, even at the height of her reforming zeal on other matters.
