Seven-time Formula 1 world champion Lewis Hamilton is said to have enquired about why Red Bull wasn't handed a penalty for altering their tyre pressures in Baku.
With Lance Stroll and Max Verstappen both suffering from tyre failures at the Azerbaijan Grand Prix, Pirelli boss Mario Isola joined the drivers for their usual briefing post the second free practice session for the French Grand Prix.
According to Auto Motor und Sport, Hamilton during this meeting sought to clarify why Red Bull didn't receive a penalty with the English driver indicating that Red Bull and Aston Martin's values were different from what Pirelli expected.
The British driver was provided with a swift answer from the FIA technical head, Nikolai Tombazis, who said, "Because it has not been demonstrated that they have not acted according to the rules."
Hamilton's title rival Max Verstappen, according to the publication, immediately assured those present on behalf of Red Bull that the Austrian team has at all times followed the guidelines set out by Pirelli.
