ALLEGATIONS of "inappropriate behaviour" against F1 boss Christian Horner come amid a power struggle at Red Bull Racing.
Horner, 50, was locked in a meeting over preparations for Red Bull's defence of their championship titles when news of a female colleague's accusation against him broke.
The woman is understood to have complained to the team’s parent company at Red Bull in Austria about "inappropriate behaviour".
Horner, 50, is now the focus of a probe being run by an independent lawyer appointed to examine her allegations.
And he faces a hearing into the allegations on Friday as the F1 champs insist they are taking the claims "extremely seriously".
The F1 chief, who is married to Spice Girl Geri Halliwell and runs the all-conquering team of world champion Max Verstappen, said: “I completely deny these claims.”

But before the investigation was revealed, it is understood trouble was already brewing beneath the surface at Red Bull Racing.
Rumours of an unrelated power struggle within the team's leadership have swirled since the death of co-founder Dietrich Mateschitz in 2022.
After the billionaire's death, Red Bull drafted in a new board of directors to oversee the business.
Former RB Leipzig CEO Oliver Mintzlaff was appointed chief executive.
Despite Red Bull enjoying its most successful season in F1 history in 2023, there was speculation of a rift between Horner and Helmut Marko - Red Bull GmBH's motorsport advisor.
Rumours even went as far as to suggest Horner was determined to get rid of Marko, 80, from the team, reports the .
The former professional driver has overseen the Red Bull driver development programme since 2005 and was a driving force in bringing Max Verstappen to the team.
But speculation was played down, with Horner only acknowledging there had been a "small difference of opinion" between himself and Marko.
He even suggested rumours may have been fanned by opponents, adding: "As we’ve tied up both championships, there’s not a lot to be talking about, so it’s very easy for others to wind the situation up.”
But Marko hinted at an internal wrangle when he commented: "I have a contract until the end of 2024 and in the end it’s the shareholders’ decision, not Christian Horner’s, and in the end it’s me who decides."
Formula 1 reporter Erik van Haren said the power struggle appears to be coming to a "climax now".
He told : "[Horner and Marko] become more and more like water and fire.
"Although, of course, in the publicity they pretend that nothing is wrong.
"Horner is, of course, the team principal and the CEO of Red Bull Racing. More than a thousand people work there. Super important for the operational side of the whole story.
"However, it is of course known to all Formula 1 connoisseurs that Helmut Marko, the Austrian, pulls the big picture. So he decides who sits in those seats.
"And yes, Horner might be the guy who would like to do that too, but Helmut is the guy who makes the big decisions.
"So if you were to ask Max Verstappen, the most important man in that team, with a knife to your throat, if you had to choose between Christian Horner and Helmut Marko, you would always choose Helmut."
Horner was appointed Team Principal of Red Bull's F1 team in 2005, and has bagged 13 world titles along the way.
Wife Geri, 51, was standing by him last night, telling pals she does not believe gossip that has been swirling for days.
Red Bull Racing’s Austria-based parent company said yesterday: “After being made aware of certain recent allegations, the company launched an independent investigation.
“This process, which is already under way, is being carried out by an external specialist barrister.
“The company takes these matters extremely seriously and the investigation will be completed as soon as practically possible.
“It would not be appropriate to comment further at this time.”
