Re: It was a very, very close decision...
In most countries significant changes to the status quo require a two-thirds majority in a referendum. That way you are assured that the change is generally wanted.
Narrow margins lead to ongoing widespread discontent as people tell themselves that it should have gone the other way.
The big danger now is a lurch to the populist right in politics all over Europe - with 1930s style protectionism and isolationism. Those already disadvantaged will find themselves even worse off in both material things and other areas like privacy. A senior policeman was on BBC Radio 4 in the "The Bottom Line" last night. He was saying that "Minority Report" pre-crime incarceration of people was the right way to go.
