Horner had remained in his post during the investigation as part of what he called a “business as normal” approach, and was in charge of the team for preseason tests last week, even as he admitted the investigation was a distraction.
Speaking before the announcement, Mercedes driver and seven-time F1 champion Lewis Hamilton said the investigation into Horner was a test of the sport’s values.
“Any allegations have to be taken very seriously. Obviously we don’t know everything that’s gone on, but it does need to be resolved as it’s hanging over the sport,” Hamilton said. “I think it’s a really important moment for the sport to make sure that we stand true to our values.”
Jim Farley, the CEO of Ford Motor Co., which is set to become Red Bull’s engine supplier in 2026, wrote to the team last week demanding a resolution to the investigation, in a letter seen by The Associated Press.
Rival team principals Toto Wolff of Mercedes and Zak Brown of McLaren last week called for the investigation to be transparent.
The 50-year-old Horner has been Red Bull team principal since it entered F1 as a full constructor in 2005. He has guided the team to six constructors’ championships and seven drivers’ championships during his time there.
Red Bull won four drivers’ titles in a row with Sebastian Vettel from 2010 through 2013, and three titles with Verstappen since 2021.
Horner is married since 2015 to Geri Halliwell, better known as Ginger Spice of the female pop group The Spice Girls.
Horner’s profile outside F1 was raised by his prominent role in the Netflix docuseries “Drive to Survive” and by his combative relationship with Mercedes team principal Toto Wolff amid a bitter title fight between Verstappen and Hamilton in 2021.
Verstappen said the investigation has not been a distraction to his bid to win a fourth successive title. The Dutch driver won a record 19 races last season and is widely considered the clear favorite this year, aided by a Red Bull car which has been significantly redesigned.
“I’m very focused on just the performance of the car myself and hopefully it (the investigation) will just be resolved very soon,” Verstappen said Wednesday before Red Bull issued its statement. “It’s a whole team effort that everyone has to stick together and work toward more success and that’s why it’s important to get everything resolved very soon.”
