Mark Colvin of the Australian Broadcasting Company has this interesting article about that rare event, the death (or, at least, decline into minor party status) of major political parties. Thanks to Sam Harley for the link.
One odd coincidence mentioned in the article is that the date of the upcoming British House of Commons election is 100 years exactly from the death of King Edward VII. Colvin traces the fall of Britain’s Liberal Party to the end of the Edwardian era.
