Deletion of Libertarian Party (UK) (6th nomination)

Comment: how did this survive so many prior AfDs? The article is source-bombed, but they're all primary sources to election results or the party's own website, deadlinks, or a couple non-trivial articles! I had difficulty finding any independent sources during a  search. Fails  pretty easily. I have never seen a guideline showing presumptive notability for a registered political party, either
