That's a pretty big change in the game and wasn't really on people's minds in 2014. I certainly wasn't thinking about the EU exit in 2014. In fact, in 2015, a 2016 EU referendum wasn't widespread knowledge.
In fact, I was shocked by the leave vote. Almost as much as the Conservative majority a year before. I'm from Salford too and the vote was a highly Leave. I'm sure those in Scotland felt that more so.
