Hamilton 'really pi**ed' at Leclerc after Mexico City flashpoint, demands Ferrari rule change

Lewis Hamilton has taken aim at Charles Leclerc after the pair's opening-lap scrap cost Ferrari a likely one-two at the Mexico City Grand Prix, admitting he was "really pi**ed" and calling for the team to establish clear rules of engagement between its drivers.

Why it matters:

Ferrari arrived in Mexico with the pace to control the race — Hamilton on pole, Leclerc third — and left with second and fourth, beaten by Max Verstappen and passed by new world champion Kimi Antonelli. Points surrendered to a team-mate's error sting far more than points surrendered to a rival, and with the pair deep into their second season together, what Hamilton framed as a one-off is starting to look structural.

The details:

• Leclerc attempted to go around the outside of Turn 4, ran out of road and cut across the grass. Hamilton, also forced wide, opened the door for Verstappen to dive into second.
• The stewards handed Leclerc a five-second penalty, served at the pit stops, which cost him the lead of the race.
• After Valtteri Bottas's suspension failure brought out the red flag, Hamilton restarted second and harried Verstappen to the flag without finding a way past.
• Hamilton was blunt about the cost: "We could have easily had a one-two, really, we had the pace to do so. When your team-mate works against you and then you lose positions like that, it's definitely tough."
• He confirmed there is no agreed protocol in place: "We don't have rules of engagement, and whether or not that will change anything from Charles' side, I don't know."

What's next:

Hamilton declined to expand publicly, saying the matter would be handled "offline" — but he was unambiguous that the status quo cannot hold: "Something needs to change for sure." Whether Leclerc sees it the same way will shape how hard Ferrari's drivers race each other over the closing rounds, and how much more the team is prepared to leave on the table.
