On Wednesday, British Prime Minister Boris Johnson announced that he had asked the queen to suspend parliament in September, reducing the amount of time lawmakers will have to debate legislation related to Brexit. John Bercow, the speaker of the House of Commons ,called the move a “constitutional outrage.” In this episode of the FiveThirtyEight Politics podcast, Helen Thompson and David Runciman discuss what qualifies as a constitutional crisis and whether they think Britain has reached that point.
