Red Bull team boss Christian Horner will make his first public appearance since taking over on Thursday. Complaints about inappropriate behavior was opposed to him.
The 50-year-old is under investigation by Red Bull but is expected to attend the unveiling of the team's new F1 car.
He was questioned by independent counsel on Friday over allegations about his conduct towards female employees.
Horner, who has led the team since 2005, has denied the allegations.
It is unclear whether Mr Horner will directly address the allegations against him in an interview at the launch of the RB20 car at Red Bull's Milton Keynes factory.
But his presence will overshadow this event. It is unlikely that he will be able to comment specifically on the allegations, but the investigation into him, driver Max Verstappen and his teammate Sergio Perez is sure to draw attention.
Red Bull's parent company said it took the allegations against Mr Horner “extremely seriously”, adding: “It would be inappropriate to comment before the investigation is complete.”
Friday's hearing ended without a resolution.
Horner denied the allegations in comments to Dutch newspaper De Telegraaf.
The investigation into Horner could take weeks, and there are even questions about whether it will be completed by the start of the season.
Pre-season testing will take place in Bahrain from February 21st to 23rd. The first race of the season will be held from March 1st to March 3rd, also in Bahrain.
Red Bull's new car has already been tested behind closed doors at Silverstone.
The RB20 is the successor to last year's RB19, which together with Verstappen achieved the most dominant season in F1 history.
