Incidentally scooping, if you've read my previous shots against FPTP you should see that I've explained on numerous occasions that I hate it as a system in principle, not because it allows the Tories to win from time to time. For example, in 2015 I was sad to see so much UKIP support, but even sadder to see that it counted for absolutely nothing in Parliament, and have said so here numerous times. Also, one of the worst-ever election results from an FPTP point of view was probably 1983 in which Labour got a ridiculously disproportionate representation in Parliament, only just edging out the SDP/Libs but getting almost 10 times as many seats. The other problem with FPTP, the seat boundaries themselves*, is something that typically benefits Labour. Please don't make the mistake of assuming that I am so partisan in my criticism of our voting system.
*As an aside, there's a case in the US Supreme Court on the subject of gerrymandering, and I was considering posting about that nearer the time it is debated there, so I'll save further electoral system rants for that thread.
