I did not make this up -

A British Member of Parliament will not appeal after failed attempt to contest election court ruling that he can no longer sit as MP because he made false statements about opponent.

That's right - an election court found that this MP lied about his opponent in the recent election, so he lost his right to sit in Parliament. If we had this procedure in the U.S. would there be ANY sitting members of Congress? Maybe 2 or 3.
