The problem---it's the *verbatim* same sentence. The BBC not only got its information from the article I wrote in 2003, but lifted my sentence word for word! (archive.org can verify that the sentence in Wikipedia long predates the BBC's use of it, and it uses an idiosyncratic grammatical construction, so there it's very unlikely to be a coincidence.)
How much do you have to copy for it to be plagiarism? I would imagine one sentence will do... Should someone contact the BBC?
