In a rare quasi-sovereign act, Queen Elizabeth II has agreed to a prorogation request by Boris Johnson which would suspend parliament from September 9th through October 14th (archived). This five week suspension of parliament during a time three weeks of recess would traditionally be taken appears motivated by a desire to prevent the commons from once again fucking up Brexit. After parliament receives a new "Queens Speech" October 14th they will have a full 15 days before the new October 31st Brexit day to try to fuck things up.

There is a small chance that at least one court in the UK challenges the prorogation and in doing so invites a minor crisis exposing the lack of sovereignty surviving in the crown.
