Sergio Perez has been handed a reprimand for an incident involving Kevin Magnussen during second practice for Formula 1’s Singapore Grand Prix.

The pair clashed in the closing stages of FP2 as Racing Point driver Perez appeared to squeeze Magnussen into the wall on the run between Turns 21 and 22.

Magnussen had looked to gain track position in the final sector of the lap before opening up a flying effort, but was forced to back out when Perez moved across on him as the duo jostled for position.

Perez subsequently came to blows with Magnussen, who in turn was pushed into slight contact with the outside wall, before radioing in to his team to check for damage.

Both drivers were able to continue in the session but the Singapore stewards were quick to call Perez before them to discuss the incident, along with team representatives from Racing Point.

Speaking about the incident, Perez said: "Basically there is not a strict rule, but there is a gentlemen’s agreement.

"Everyone is opening up their laps. I had I think one of the Mercedes ahead, a few seconds, so I’m opening the gap, and I didn’t expect him to try to go there. I think we touched, and that was it."

The Mexican added he would "definitely" speak to Magnussen about the incident to seek clarification. 

"We have to figure out, some drivers they stick to the gentlemen’s agreement, but the issue is some others, they don’t," he added. "I think it’s something we have to come up with, whether we have to implement a rule or whatsoever. It’s not good to see that."

Perez ended up as the quickest Racing Point driver in 13th place, some 2.102s off the pace managed by session leader and world championship leader Lewis Hamilton.

Magnussen finished the day’s running in 19th in what was an uncompetitive showing for Haas. Teammate Romain Grosjean was only a tenth quicker in 17th, with the Haas drivers separated by George Russell’s Williams.
