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

Horner is facing allegations of inappropriateꦓ and controlling behaviour towards a female colleague and is b🌃eing investigated by Red Bull’s parent company Red Bull GmbH.

The 50-year-old has repeatedly d🅰enied the accusations and contin⛎ues to work for Red Bull.

Horner attended both the shakedown of Red Bull’s new RB20 car at Silverstone and its official laဣunch 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 underwa🌺y on Wednesday.

Horner was subject to hours of questioning during an interview with an independent lawyer on F🐻ebruary 9 but the hearing ended without a resolution.

Marko has moved to def🍎end Red Bull’s delay in concluding the probe✱.

"As you know, this is an internal investigation,”ꩵ Marko told Red Bull’s ServusTV channel.

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

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

Meanwhile, F1 has 🍸urged Red Bull to provide clarity on the investigation at the “earliest oꩲpportunity”.

"We have noted Red Bull has instigated an independent investigation into internal allegations at Red Bull Racing," a st✅atement released on Sunday read.

"We h𒁃ope matter will be clarified at earliest opportunity, after a fair and thorough process. 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” w🍬ith their probe into the controversy surrounding Horner.

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.
