I'm not surprised looking at the results, I had a feeling that the vote would be regional, with the relatively prospersous south voting to remain and less well off areas voting to leave. I suspect the whole immigration issue played a big part unfortunately, in or out of the EU immigration isn't going to change. I also suspect that some Labour voters have become disillusioned and shifted their allegiance.
British politics has sunken to an all time low and there will be another round of complete bull shit from all parties in the up and coming general election.
Will EDF cancell or moth ball Hinkley Point, it's run into serious engineering issues, will the Swansea tidal barage be scrapped. Those are only two major engineering projects I could think of, we will have to wait and see.
