I found this on a Facebook Group and it's brilliant!
Labour: The kingdom of men, a vast and influential group. Known for their hardy nature and love of the common man.
Conservatives: The Elves, a large group who base their lives on traditional values.
Liberal Democrats: The Hobbits, a small group who have nice ideas. They can’t really compare to the other forces on an open front, but somehow they hold the fate of Middle-Earth.
UKIP: The Dwarves, a small group who are fiercely territorial and prefer to distance themselves from the rest of the world.
Green: The Ents. This one is pretty self explanatory…they’re trees…
Independent: The independent politicians are the mercenary leaders who sit around places like “The prancing pony” swapping courageous stories.
SNP, Sein Fein, Plaid Cymru: Easterlings and Haradrim, vaguely external political forces that frequently come to loggerheads with the other kingdoms of man.
Monster Raving Looney party: Tom Bombadil…enough said.
The eye of Sauron: Sauron is usually either China, Russia or Afghanistan depending on your own personal “nuclear threat” views.
Other important characters:
David Dimbleby: Gandalf (Think about it…it’s obvious)
The BBC: The white council, the wizards
