Red Bull motorsport advisor Helmut Marko has broken his silence over the investigation surrounding F1 team principal Christian Horner.

Horner is facing allegations of inappropriate and controlling behaviour towards a female colleague anꦅd is being investigated by Red Bull’s parent company Red Bull GmbH.

The 50-year-old has repeatedly denied the accusations ⛦and cont꧑inues to work for Red Bull.

Horner attended both the shakedown of Red Bull’s new RB20 car at Silverstone and its official launch event in Milton Keynes💟 last week.🐻 He has travelled to Bahrain and is expected to be on the pit wall when F1 pre-season testing gets underway on Wednesday.

Horner was subject to hour🔯s of questioning duri൩ng an interview with an independent lawyer on February 9 but the hearing ended without a resolution.

Marko has moved to de🐲fend Red Bull’s delay in concluding the probe.

"As you know, this is an internal investigation,” Marko told Red Bull𒊎’s ServusTVꦰ channel.

"The sooner a result is available, the better b🐻ecause of course, rumours and other stories are bound to sprout due to the long duration.

"[But] I think Red Bull has reacted very well in this mℱatter. The long duration of this investigation is not their fault. They are endeavouring to [have] a fair investigation and then react accordingly.”

Meanwhile, F1 has urged R𝔍ed Bull to provide clarity on the investigation at the “earliest opportunity”.

"Weও have noted Red Bull has instigated an independent investigat🔯ion into internal allegations at Red Bull Racing," a statement released on Sunday read.

"We hope matter will bꦯe clarified at earliest opportunity, after a fair and thorough proceဣss. Will not comment further at this time.”

Red Bull’s engine partner Ford is reported to have sent a private letter asking them to be “transparent” and “rapid” with their probe into the controversy surrounding H🌜orner.

Ford will team up with Red Bull from 2026 but the Financial Times reports 💖the American car giant could yet walk away from the deal.
