Doubt it. The SNP has been caught out telling blatant lies like how Scotland’s shipbuilding industry (which relies entirely upon Royal Navy contracts) will be safer under independence, despite both BAe Systems and the Ministry of Defence both saying that they will reconsider closing English Shipyards and build them there instead.
Most polls seem to suggest that over 50% will vote ‘No’ and the Yes Vote usually struggles to get past 30%. For the Yes Campaign to win, you would have to assume that a lot of pro-Union sympathisers won’t bother to vote (unlikely) and that almost all the undecideds will vote ‘yes’ (again, unlikely). At this point, I think it would take a political event of cataclysmic proportions to persuade the Scots to vote for Independence in September.
There are some military contractors in Scotland who will probably relocate if they get independence.
There have also been allegations of intimidation being used. Pro-Union businesses have been threatened with “retribution” if they dont support the “right” side.
