Go on then, explain.
Oh, and being condescending just shows you up.
Well stop trying to act like you know better than you do and I won't be so condescending. You could have asked me to explain instead of trying to contradict me with such poor evidence and making statements as if they were already proven. FPTP doesn't favour any one party in the sense that one party must necessarily win more seats per vote than another - as you were trying to say. This is the marginals issue I've mentioned constantly. If Labour wins them then they get far more seats than their votes suggest they should. If Conservatives do, then the situation is reversed.
In the 1983 election, the Conservatives won 42.3% of the vote but won 61.1% of the seats. So 1.44% of seats for 1% of the vote. Whereas Labour won 32.2% of the seats with 27.6% percent of the vote. So, 1.17% of the seats for 1% of the vote. Our electoral system hasn't changed one bit though. Wouldn't be surprised if it happens again this election and the tories win more seats per vote. This is the nature of FPTP. Where it does benefit the tories though is that we have three parties and two of those parties have always been more inclined to form election pacts and joint cabinets etc. The outsider of that group is the tories and that's where FPTP benefits the tories. The Liberal (Democrats) are always the party that suffers. By happy chance, 1983 is the best demonstration of this. SDP-Liberal Alliance won 25.4% of the vote and received just
3.5% of the seats. That's 0.14% of the seats for 1% of the vote. So, FPTP doesn't favour the tories because of the nature of the system but because of the relations between political parties, most notably those between Labour and the Liberal (Democrats).
