The leadership in question is voted in by a much smaller number than what US elections manage. FPTP means not only are some regions completely devoid of the winning party, but have never voted for them as a local majority in decades, if ever. The secondary and tertiary problem with this situation is that neither do the alternative parties ever really offer anything different, remember before the current Labour gov the Tories were in power for about 14 years, but also that the population never really seems to stick to actual alternatives when "offered" them. So it swaps back between Red or Blue just like in the USA except the differences between the two now seems even less obvious than when Blair rewrote the playbook.
