In the final stages of the race, Alonso was stuck behind his Alpine teammate Esteban Ocon in seventh when he started to feel the pressure of Alfa Romeo Bottas driver behind him.
With just over a lap of the 70-lap race remaining, Alonso aggressively defended the Finn as he snuck down the long straight before the final chicane, which forced Bottas to forfeit a potential move.
Alonso held on to finish seventh by just three tenths, but after the race he was summoned by the FIA stewards for the decision.
The stewards judged that the Spaniard “made repeated changes of direction” and thus forced Bottas to lift, which they considered contrary to the regulations, in particular article 2 b) of chapter IV appendix L of the FIA International Sporting Code.
Alonso was given a five-second penalty, which moved him from seventh to ninth place, behind Bottas and his Alfa Romeo team-mate Zhou Guanyu.
The incident not only cost him and Alpine four precious points, but also earned him a penalty point, taking his total over the past 12 months to six.
The Stewards’ verdict read: “Between turns 10 and 12, on the penultimate lap of the race, car 14 made repeated directional changes to defend against car 77 which had to lift at one point and briefly lost momentum.
“While noting the driver’s point that at no time was car 77 next to car 14, the Stewards consider this to be a clear breach of the above regulations. The Stewards therefore impose a five-second penalty in line with that imposed for a similar incident in Australia in 2022.”
