@IndyRichard I would suggest that it's probably that Scotland is over represented with seats in Westminster per head of population. Scotland was also much more pro labour in the past so put the two together and there's no conspiracy. Of course I understand that many wish Scotland to be separate from R-UK and one could argue that Labour would be more sympathetic to the viewpoint going forward.
All that said, everyone should vote (or not) according to their own point of view
