"We won't have a stage winner. We will give the points for the mountain classification and the intermediate sprint, but not on the finish line."

Two seconds of that offset can be accounted for by a slower pit stop, the other five by the extra lap on worn intermediates.

Piastri fitted the medium tyres while Norris had to do an extra lap on a drying track on highly worn intermediate tyres.

That was because it was not a particularly good tyre, while the intermediate was.

"Some of the strongest evidence is against tariffs on intermediate inputs like steel and aluminium, finding they are much more harmful because they increase the cost of production in the United States," she said.
