Christian Horner will make his first public appearance on Thursday since an investigation was launched into an allegation of “inappropriate behaviour” against the Red Bull team principal.

The embattled boss is due to attend the world champions’ car launch at their Milton Keynes headquarters following the accusation by a female colleague which surfaced at the beginning of last week. Horner, 50, categorically denies the claim.
