Max Verstappen will not leave Red Bull, according to the crisis-hit Formula One team’s group CEO Oliver Mintzlaff.

Verstappen cast doubt over his future when he claimed he will quit the world champions if motorsport adviser Helmut Marko is forced out.

The PA news agency understands 80-year-old Austrian Marko, an instrumental figure in Verstappen’s career, faces a Red Bull investigation following the probe into claims of “inappropriate behaviour” against Christian Horner.

Verstappen’s deal with Red Bull runs until 2028 and, when asked by the PA news agency ahead of Saturday’s Saudi Arabian Grand Prix if the Dutch driver will remain with the team, Mintzlaff replied: “Of course. He has a contract.

“Max is a great driver and hopefully we will win tonight. I am here just for racing. That’s it.”

Horner’s female accuser was suspended earlier this week as a direct result of Red Bull’s inquiry which exonerated the 50-year-old team principal.

Marko is employed by the F1 team’s parent company, Red Bull GmbH.

Asked if he could be suspended following the race in Jeddah, he told Austrian broadcaster ORF: “Ultimately, I’ll decide for myself what I do. The theoretical possibility always exists.”

PA has approached Red Bull Racing for comment.

“I have a lot of respect for Helmut, and what we have achieved together,” said Verstappen after putting his Red Bull on pole position for Saturday’s race.

“It goes very far. My loyalty to him is very big, and I have always expressed this to everyone within the team, everyone high up, that he is an important part in my decision-making for the future.

“It is very important that he stays. I feel like if such an important pillar falls away, and I have told the team this, that it is not good for my situation as well.

“Helmut built this team together with (Red Bull’s late owner and founder) Dietrich (Mateschitz) from day one, and he’s always been very loyal to the team.

“It is very important that you give the man a lot of respect for what he has done, and that comes back to loyalty and integrity, so it is important that he stays.”

Red Bull’s three-time reigning world champion Verstappen, speaking after qualifying on pole for Saturday’s race in Jeddah, said: “I have a lot of respect for Helmut, and what we have achieved together.

“It goes very far. My loyalty to him is very big, and I have always expressed this to everyone within the team, everyone high up, that he is an important part in my decision-making for the future.

“It is very important that you give the man a lot of respect for what he has done, and that comes back to loyalty and integrity, so it is important that he stays.”

Verstappen did not mention Horner’s name as he defended Marko.

Horner, team principal at Red Bull since 2005, said on Thursday he is certain Verstappen will see out his long-term contract with Red Bull, despite the ongoing controversy.

Verstappen’s father, Jos, claimed Red Bull will “explode” if Horner remained in his role.

Verstappen, whose deal runs until 2028, has been linked with a move to Mercedes to replace Lewis Hamilton next season. Hamilton said earlier this week that the 26-year-old Dutchman is on Mercedes’ “list”.

Max Verstappen has beefed up his personal security as he prepares for a hostile reception at Red Bull team-mate Sergio Perez’s home race in Mexico.

Verstappen was jeered by Perez’s supporters at last weekend’s podium presentation in Austin as the triple world champion celebrated his 15th win of the season.

Chants of “Checo, Checo” – in support of Perez – were also audible during the Dutch national anthem.

A crowd of nearly 400,000 are expected at the high-altitude Autodromo Hermanos Rodriguez over the course of the weekend, with practice starting on Friday and it is understood Verstappen will be flanked by multiple security guards in the paddock.

Perez’s fans are unhappy Verstappen did not help the Mexican secure second place in last season’s championship after he ignored a team order at the penultimate round in Brazil.

Perez has won only twice this season – his last victory in Azerbaijan on April 30 – with Verstappen racing to his third title in as many years.

The paddock in Mexico City has become one of the most manic on the calendar, with drivers mobbed as they make their way from the motorhome to the garage.

And Perez is also expected to have a bigger entourage than normal to cover-off his enthusiastic fanbase.

Red Bull team principal Christian Horner and the team’s motorsport advisor Dr Helmut Marko will also be accompanied by security guards.

Speaking after last weekend’s race in Austin, Horner said: “I don’t think Max is going to get the warmest reception in Mexico, but that is water off a duck’s back to him.

“One year you are the villain and the next year you are the hero.”

Perez heads into this weekend’s round 206 points behind Verstappen. However, he is 39 points clear of third-placed Lewis Hamilton, who was disqualified from second at the Circuit of the Americas for running an illegal floor on his Mercedes.
