And if the Callahan government had not betrayed the people of Scotland in the 79 referendum there would have been no withdrawal and no motion of no confidence. Anyway, the Callahan government were already over 4 years into their term so an election would have been called that same year anyway and if you think Labour would have won ANY subsequent election then you're an idiot.
Perhaps you should actually read up on the events for yourself rather than just unthinkingly parroting what you hear from other unionist non-thinkers.
