Horner was cleared of any wrongdoing following an internal investigation by the team’s parent company after he was accused of ‘inappropriate behaviour’ towards a female colleague.
However, Newey is said to be unsettled by the matter which has caused a power struggle within the team involving the Thai side of the ownership (who backed Horner) and Red Bull GmbH (who initially wanted to remove Horner from his position).
Newey has built title winning cars with Williams and McLaren and has been a stalwart for Red Bull since he joined the team in 2006, designing the cars that won them their seven drivers’ titles and six constructors’ championships.
