Red Bull’s investigation into Christian Horner’s conduct may be fast-tracked so that a conclusion is reached by the end of next week, according to reports. The 50-year-old is being probed over allegations of inappropriate behaviour, which he vehemently denies after a female colleague issued a complaint to Red Bull’s parent company in Austria.

A new allegation has since been reported by a Dutch newspaper, which has threatened to deepen the crisis at Red Bull just weeks before the start of the new season. The defending champions are now hoping for the saga to be wrapped up over the coming days, according to The Times, with Red Bull’s hierarchy looking to accelerate the investigation process.

It was previously reported that it could drag on until after next month’s Bahrain Grand Prix, with Horner likely to face subsequent rounds of questioning after being grilled by a top lawyer last week. However, there is now said to be a desire within Red Bull to conclude the process as quickly as possible.

Horner, who has been at Red Bull since they entered F1 in 2005, is thought to have instructed lawyers to assist him in contesting the new allegation. However, the accusation is said to have done little to ease the uncertainty over his future, which is reportedly hanging in the balance.
