Calling "FPTP" a "system" is an INSULT to the term "system" - that is what ANYONE NORMAL would be screaming to the English people every second of the day.
AV is the wrong system. And FPTP is NOT a system.
UNDER "FPTP" - IF you vote for someone other than the winning candidate in your seat - your vote COUNTS FOR NOTHING WHATSOEVER.
BASICALLY it is COMPARABLE to a night at the dogs. But with speeches.
