Boris Johnson will cease to be an MP with immediate effect, triggering a by-election on his seat. Johnson had been facing a parliamentary investigation for months that analyzed whether he lied to MPs about banned parties.

Johnson accused the committee of being the "very definition of a kangaroo court [a judicial body that does not respect due process]." "In retrospect, it was naïve and trusting of me to think that these procedures could be remotely useful or fair," Johnson said in a statement.
