Horner has been under investigation by Red Bull’s parent energy drinks company following allegations made against him by a female employee.
Red Bull appointed an independent barrister to look into the matter, and interviews have taken place with Horner and other individuals involved to try to get a clear picture of the situation.
Horner has strongly denied any wrongdoing over the matter.
There has been no official comment from Red Bull since the start of the probe, but there are suggestions a decision on the outcome of the investigation could be imminent – and may even come ahead of track action commencing at this weekend’s F1 season-opener in Bahrain.
While there has been a great deal of uncertainty over the situation, Horner has continued in his role as team principal.
He attended last week’s pre-season test in Bahrain and was in the team’s Milton Keynes factory this week to continue preparations for the start of the campaign.
