It seems that a lot of postal votes for expats abroad did not arrive in time, and those affected also want a re-run.

If they had all arrived to be returned in time  I wonder how much influence on the outome that would have had. Some would have voted leave but I imagine that a higher proportion would have voted remain.

What a mess this referendum has been in more ways than one.
