Due to the extension of a state of emergency, there has been a lot of official opposition to the event going ahead. Despite the opposition, the organizers have stated their intention to go ahead. It’s worth noting that the organizers waited until the last second before canceling the 2020 version, even though it was obvious to anyone that the event wasn’t going ahead.
