Just the article I needed to challenge my initial flabby-minded boomer reaction! Thank you :)

"Therefore, the majority of the country voted for the manifesto."

Logic alert! Your own source tells us that "The party's vote share was 33.7%, the lowest of any majority party on record, making this the least proportional general election in British history according to the Gallagher index."

Unless I misunderstood, and you were being ironic? To avoid confusion, please capitalise any text that is meant to be subtle ;-)
