The UCI has nothing to do with this case (not they actually know how to do their job), all the political bullshittery was between the FCI and the other parties involved.https://cyclinguptodate.com/cycling...ionica-race-cancelled-only-hours-before-start
Tuttobiciweb reports that mistakes were made from the side of the race organizers.
What this means exactly is said to be problems with traffic technical guidance and the absence of an UCI jury. There were no TV rights agreed on for the race and it is possible that there was an internal clash regarding the UCI and the Italian Cycling Federation. Moreno Argentin, race director, confirmed now with hours to go that the rumour of a possible cancellation had been confirmed.
(It's Italy, these things happen!)
I hope the truth comes out, but it sounds like a "Trump" move. We await the press conference.
