With the SNP declining could we see results like this again?
This from GE1992 is really quite extraordinary with the winner on just 26% of the vote and the Tories in fourth place only 3.4% behind.
The rise of the SNP at GE2015 has rather obscured what happens under first past the post when in some seats four parties have a chance of taking the seat.
My guess is that with the drop in fortunes for the SNP that we might see results similar again though not necessarily this close.
